Range Rover Brakes: Inspections and Repairs

Range Rover

Pawlik Automotive are 15 time winners of "Best Auto Repair in Vancouver, BC" as voted by their customers.

Mark: Hi, it’s Mark from Top Local Lead Generation, we’re here with Bernie Pawlik of Pawlik Automotive they’re 15 time winners of Best Auto Repair in Vancouver as voted by their customers. We’re talking about Range Rovers brakes today. How’re you doing Bernie?

Bernie: I’m really well.

Mark: So we titled this Inspections and Repairs on Range Rovers, is there anything unique about Range Rover brakes?

Bernie: Well I’d say the one unique thing about Range Rover brakes is they’re really big, I mean Range Rovers are really a sports car, sport utility vehicle, a lot of them have supercharged engines, lots of horsepower, luxury items galore, air ride suspension, lots of options and controls and these vehicles weigh a lot so they put big brakes in so you can be going 100 miles an hour and stop the car really fast. So that’s what’s unique about Range Rover brakes. Actually I have a couple samples from a job we did the other day so you can just get an idea how big these are: this is a Range Rover brake pad and it’s huge, I mean just for comparison’s sake, this is a brake pad out of a Nissan Versa which is a small car but none the less, it’s a pretty good size brake pad, it’s sort of an average Japanese car brake pad. I don’t have any American vehicles to compare but this Range Rover brake pad is larger than you’ll find in a Ford F350 or for a Chevy Suburban, this brake pad is twice the size. The brake rotors are also massive on a Range Rover as I grunt as I lift this thing. I don’t have a comparison rotor but this is a huge brake rotor so, a lot of work lifting that.

Mark: So that’s definitely bigger than the rear rotor on the Nissan Versa.

Bernie: Oh absolutely, yes much so and I mean even the thing about a Chevy Suburban you know which is a big truck, you know the brake rotors are substantially smaller.

Mark: So how long will they last?

Bernie: Well you’d think with big brakes that they would last a long time but the interesting thing is they don’t. We see Range Rovers sometimes with as little as 20 thousand, 25 thousand kilometers where the brakes are worn out. They don’t last a long time. I ofter wonder to myself because they are so large why they wouldn’t last longer but I can only assume that just the weight of the vehicle wears them out quickly, they’re big brakes, there’s lots of area to dissipate the heat so they should last a long time. The rotors wear along with the pads as well so it’s not like they use a really soft pad you know because the rotors are wearing at the same time so um, they don’t last, they don’t last as long as you think they would.

Mark: So what parts do you replace on the Range Rover?

Bernie: Well typically I’ve just shown you pretty much everything that we do: the brake pads and the rotors usually get changed every time. Brake fluid gets flushed every 2 to 3 years and also on the Range Rovers these vehicles do have an electronic brake pad wear sensor and you know as long, if the lights on and they’re worn out then we replace those as well. Usually calipers last a long time in these vehicles, it’s very important not to let these get metal on metal though like to wear them fully out because the calipers are just outrageously expensive but we’ve yet to do one. They last a long time but you know if you have one that’s 10 or 15 years old at that point you may need to start changing calipers or brake hoses but other than that it's pads and rotors.

Mark: Sorry, any difference on your inspection times?

Bernie: No, they’re the same, yeah it’s the same, the same inspection we give on you know any other vehicle, same techniques and measurement. As for inspection intervals, you know they’re generally due for a service around every 10 to 20 thousand kilometers so you know if it has a 20 thousand kilometer oil change interval you definitely want to be inspecting the brakes every time that comes around.

Mark: So if you’re looking for service for your Range Rover the guys to call are Pawlik Automotive in Vancouver. To book your appointment give them a call at (604) 327-7112. They’ve just expanded, they’ve got a lot more space so give them a call or check out their website pawlikautomotive.com. Thanks Bernie.

Bernie: Thanks Mark.

2011 Range Rover Sway Bar Replacement

Talking Range Rovers with Bernie Pawlik, owner and master mechanic at Pawlik Automotive in Vancouver, BC. Pawlik Automotive are 15 time winners of best auto repair shop in Vancouver as voted by their customers!

Friday’s featured post is a rear sway bar replacement on a 2011 Range Rover Sport, brought to us by a client from Vancouver.

Range Rover Sway Bar

2011 Range Rover

Many items found on Range Rovers are far from simple, and the rear sway bar is no exception. The Range Rover’s sway bars are part of the vehicle’s stability control system and incorporate a hydraulic unit capable of isolating both sides of the bar.

Our featured vehicle came to us with the dash warning light on for a stability control malfunction. Diagnosis found the fluid level low in the underhood reservoir and we traced the cause to a leak in the rear sway bar hydraulic unit. This is a non-repairable part and must be replaced as a complete unit. As you might guess, it is pricey. Though the labour is not outrageous the part is buried deep under the rear of the vehicle above the differential and requires the body to be lifted from the frame to remove and reinstall the unit.

Range Rover Sway Bar

Rear sway bar assembly: Note the hydraulic unit which isolates both sides of the bar.

Sway bars are found on most cars and light trucks: their primary purpose is to reduce body roll while cornering and making high speed maneuvers. System components include a metal bar attached to the vehicle frame and extending to each control arm or strut by an end link. Bars connect both sides of each axle together. While this generally works just fine this is a mechanical component that functions the same under all conditions. Sometimes it is advantageous to change the tension of the sway bar, even disconnecting the two sides of the car completely. This is what the Range Rover’s system does.

When you buy a Range Rover among the many amazing features that you receive is a very advanced suspension system. The vehicle features air suspension which allows the driver to adjust the vehicle’s height. Terrain control is another huge feature. As the driver you can adjust a knob located on the center console for different road and climate conditions: steep hills, snow & sand, rocks or just normal pavement. This system incorporates a number of components and controls the transfer case and differentials; it controls suspension height and response, and it also controls the sway bars. It can even decouple them to allow individual, extra travel in the suspension system: very useful for extreme off road use.

While 99% of Range Rovers in the Vancouver area never go off road they are one of the most capable vehicles to do so. It’s hard to blame someone for staying on the paved highway: for over $100,000 and with beautiful paint and nice low profile tires and wheels it would be a shame to scratch up such a nice SUV.

2006 Range Rover – Fuel Pump Replacement

Range Rover

Our latest featured service is fuel pump replacement on a 2006 Range Rover, brought to us by a client from Dunbar, Vancouver.

Range Rover

2006 Range Rover

This Range Rover arrived at our shop by tow truck following a conversation with our client. He called explaining that his engine was cranking over but would not start. I explained to him that towing the vehicle to the shop was really all that we could offer. This is the case with most modern cars: due to their complexity there is little that one can do on the roadside, though sometimes you get lucky. On a positive note, modern cars break down rarely when compared to cars of the past.

After the vehicle arrived we diagnosed the concern. There are 3 basic things required to make an internal combustion gasoline engine run, assuming of course that the starter is turning the engine over: these are: compression, spark and fuel.

Based on experience we can usually get a pretty good idea of engine compression just by listening to the engine cranking over. In the case of this Range Rover it sounded good.

Next tests were for spark, fuel injector pulse and fuel pressure. Spark and injector pulse were good.

Fuel pressure is tested by connected a fuel pressure gauge to the engine. Here we found no fuel pressure and this was why the engine failed to run.

At this point we were left with a few more tests to see if the pump was dead or there was a wiring or electronic issue present causing the pump not to run.

We verified that all things electrical were good and the pump was dead.

Replacing the fuel pump on this Range Rover is timing consuming due to the use of a saddle tank which incorporates two fuel pickups and gauge sending units. Fortunately the access is under the rear seat which makes the job a little easier.

Range Rover

Fuel pumps on almost all vehicles are located inside the fuel tank. There are several reasons for this: ease of manufacturing being one; the other is a performance advantage to having the pump at the source of the liquid instead of it having to suck the fuel from the tank. This is more efficient and uses less energy

The disadvantage is in the access. As I mentioned this Range Rover is easier due to in car access. Many cars are not so easy: you must remove the fuel tank to change the pump.

Should you ever experience your engine cranking over and not starting like this Range Rover did I can offer a couple of tips to you. Be sure to check your fuel gauge. On more than a few occasions we’ve had vehicles towed in with a possible fuel pump concern only to find the tank is empty. How might you know if it is your fuel pump? On most cars when you turn your key to start the fuel pump will run for a couple of seconds and if you listen closely to the underside of your vehicle you can hear a faint humming sound. It can be tricky to hear this but if you can, and you even suspect that you are low on fuel you might be best to get a Jerry can and a few liters of fuel into the tank: it might save you an expensive tow and diagnosis.

One other tip about fuel pumps, and this applies to all cars and light trucks: don’t run your vehicle low on fuel: the moment the low fuel warning light comes on, fill up your tank. Adhering to this will maximize the life of your fuel pump.

Range Rover

Fuel gauge reading empty and warning light on. This is not a good scenario. Do not continuously run your vehicle this low on fuel as it will shorten the life of your fuel pump.

2006 Range Rover Sport – Power Window Repairs

Range Rover Sport

Our featured post is power window repairs on a 2006 Range Rover Sport Supercharged, brought to us by a client from Burnaby.

This 2006 Range Rover Sport arrived at our shop with a myriad of concerns ranging from air suspension system inoperation to worn suspension control arm bushings and front brakes, to name just a few. Another concern was that both front power windows didn’t operate. Our client had just purchased this vehicle for a low price due to the repairs needed and its neglected condition.

Our first step was diagnosis and from these tests we verified that there was no ground to the power window motors. All other circuits and components were good. Knowing this, our next step was to find the bad ground. This could have been a daunting task however through doing some online research we found that this was a common concern and the faulty ground was usually found in the wiring harness running along the floor near the passenger’s seat.

Armed with this useful information we removed the passenger seat and compartment trims. We pulled up the carpet and found a lake on the floor and a drenched wiring harness. Untaping the wiring harness we found the cause of the concern. The ground connection had disintegrated. We soldered the wires together and retaped them. Next step was to dry out the water, the carpet and especially the wiring harness.

Range Rover Sport

Three wires for the front power window ground that we found broken apart. It is difficult to see how they were connected in the first place. As this fault is common they likely used a very poor connector that is prone to disintegration because we found no evidence of it. Our repair is permanent: we soldered all wires together.

Water doesn’t just get into a vehicle on its own so along with the wiring repairs we sought out the cause of the water leak and found it coming from the sunroof. The drains were plugged, a common problem on this and many other vehicles. After cleaning the drains we verified that all water flowed down the drain hoses and no further water leaked into the vehicle.

Final steps were to reassemble all removed components and doing a final retest: all the windows worked as they should. While this was quite an involved job it was relatively inexpensive compared to what could go wrong with the power windows. Thanks to the common occurrence of this concern and readily available information it kept the diagnosis to a minimum.

2002 Land Rover Discovery – Coil Springs and Shock Absorbers

Land Rover Discovery

Our featured post is replacement of front and rear coil springs and shock absorbers on a 2002 Land Rover Discovery.

Land Rover Discovery

2002 Land Rover Discovery

Our client had recently purchased this vehicle and while doing a comprehensive inspection we found 2 broken coil springs. The shock absorbers, which were the same vintage as the springs, also needed replacement .

There are several different types of suspension springs used on trucks: torsion bar, leaf and coil. Additionally, some fancier vehicles, like the Range Rover use air springs which allow height adjustments in the suspension system. The Land Rover Discovery is a more utilitarian 4 wheel drive vehicle and uses coil springs.

Shock absorbers remove the oscillations of the springs. When your vehicle hits a bump it bounces on the spring and continues to do so until the energy of the bounce is gone. It may take several up and down movement for all of the energy to be used up. The shock absorber stops the bouncing and makes the vehicle ride smoother. If you’ve ever ridden in a vehicle with completely blown shocks you will likely feel sick from the continuous and uncontrolled bouncing.

For springs we had only stock replacement units available but for shocks there were several options. After discussing the various offerings with the owner we chose to install Bilstein shocks which are original equipment on this vehicle. These are a very tough and durable shock absorber that will last for many years and be able to handle the roughest roads. While the Bilsteins are substantially more expense than most other aftermarket shocks they are very worth the additional cost.

After replacement of the springs and shocks our client’s Land Rover Discovery sat higher and sat evenly. The ride was superb and the truck was ready for any road conditions.

How Much Service do Land Rovers and Range Rovers Require?

Land Rover Discovery

Mark: Hi, it’s Mark Bossert from Top Local Lead Generation. We’re talking with award winning, 12 times voted Best in Vancouver by their customers from different publications in Vancouver, Mr. Bernie Pawlik from Pawlik Automotive. How’re you doing today Bernie?

Bernie: Excellent, and you?

Mark: I’m good. So we’re doing an early morning one today and we’re going to talk about Land Rovers and Range Rovers, pretty fancy vehicles, seems to be a lot more of them around these days – So do you see a lot of them in your shop?

Bernie: Yeah, we do. We work on plenty of Land Rover vehicles. They’re really nice vehicles, generally very tough and luxurious for sure, but they are somewhat problematic, which is kinda good for us.

Mark: So, problematic, doesn’t spending a lot of money on a high end vehicle ensure a trouble free ride?

Bernie: Definitely not. I think it’s kind of interesting, at least with European cars, there seems to be a correlation between how much you spend on a car and how much service you have to do. You’d think to yourself, if you buy a good quality car you’d have less problems but it seems to the exact opposite. In all fairness, in a complex vehicle, a luxury car, there’s a lot more things that can go wrong. But it seems like they don’t make them quite as well in some ways, especially when compared to the Japanese luxury cars like Lexus and Infiniti, they seem to be a little more trouble free.

Mark: So what sort of issues do you see with Land Rover and Range Rover?

Bernie: Well, there’s lots of stuff and I’ll say they’re getting better with each passing year. Going back to the mid to late ’90’s, there were quite a few of engine problems with their V8 engines, they have cylinder liners that would sometimes fail, not a lot, but when they do you have to replace the whole engine, they’re not something that can be readily machined like a lot of standard V8 engines could be. Oil leaks from the valve cover gaskets and a number of different spots are common. In the early 2000’s some of the Range Rovers had a BMW V8 engine which you think would be great but they’re actually not the best V8 engine. There’s a lot of problems with them, I mean they’re good when they’re younger but as they get older, they start to get oil leaks and coolant leaks and they’re pretty expensive to fix. So they got away from all that, it seems like the engines these days are pretty good in the Land Rover and Range Rover car, or trucks, I should say.

Mark: What other kind of issues do they have?

Bernie: Well, most Land Rovers, and all Range Rovers certainly, use air suspension which is great because you can change the height of the vehicle for different road conditions, or if you’re going down the highway, the vehicle can drop down for more stability, it’s a great feature, but a lot of things go wrong with air suspension. There are sensors on each corner of the car, there’s an air bag which is basically a giant air spring on each corner and eventually those bags will leak. It can take quite a few years, but they do leak. Probably the biggest problem the compressors that uses an air compressor to fill the air bags and over time, the compressors will fail for various reasons. But one model of Land Rover, or sorry Range Rover, they actually put the air compressor in the trunk underneath the spare tire, which is a great spot for it. Other models, they put the air compressor outside the vehicle, underneath the vehicle, inside a somewhat weatherproof box, but of course it’s not fully weatherproof, water gets in eventually and wears it out. And it’s just a stupid place to put it because this is an off road type of vehicle which is designed to go off road and that’s the last place you want to put an electronic device. Anyways, that’s what they’ve done and you have to deal with it.

Mark: So are these good off road vehicles?

Bernie: They certainly are, they’re built very tough, they’ve got solid frames, large drive train components. One exception is the Freelander or the LR2, which is a replacement of the Freelander. These are more car like models, but the main LR3, LR4 Land Rovers and the Range Rovers, they are definitely big truck type vehicles. Land Rover has that reputation for being an off road vehicle, you see them driving through the Serengeti, they have a well deserved reputation. You can pretty well take a lot of the older ones pretty much anywhere, they’re simpler vehicles, but with a lot of these more modern ones, most people, they never get off road, they’re just a nice little luxury ride around town or up to Whistler for the weekend. But the great thing about it is if you get tired of the night life up at Whistler, or sitting around in your hotel room, you can always go off on some rough logging road and go exploring and you’ll get there and back most likely. the only thing I’d worry about is scratching the paint and maybe wrecking the nice low profile tires and wheels. We have one client who has an LR3, he goes out hunting with his buddies, it has the air suspension and everything so you can adjust the height ride. He goes out quite frequently and uses it for what it’s meant for, drives around daily and it’s a tough truck, it works really well.

Mark: So you mentioned something about the Land Rover Freelander

Bernie: I did, and this is the only vehicle we’ve worked on in our shop in years that I can say, is a piece of junk. It’s a horribly built vehicle and is really actually the only vehicle I can think about other than maybe like an older Hyundai or a Lada – that I can say is a piece of junk. The engines in the Freelander, at least the ones sold in North America uses a strangely designed V8 engine and what happens with this engine is it uses cylinder liners that are held in place with some sort of strange adhesive or glue. And eventually after not too long, maybe five years the liner fails, or the glue fails, and the cylinder liner starts flopping around and that causes the head gasket to leak. The only way you can fix it, is to replace the engine with an engine from Land Rover. There is nobody who can rebuild it, nobody can fix it, and these engines rebuilt by Land Rover may well be new engines. The problem is so bad apparently, that Land Rover was actually buying the vehicles back from customers and actually just sending the vehicle off to get crushed. I find that just appalling when I think about it, I mean, any vehicle built should last for at least twenty years, if you take good care of it – if you choose to keep it that long. But the fact that some of these vehicles you wouldn’t even get a 100,000 km out them, before sending them to the scrapper is horrible.

Apparently in Europe they sell the Freelander with a diesel engine which is really reliable, so it’s just the engine offering that they put in it makes it a crappy vehicle around here. Now they replaced the Freelander with the LR2 which is a much nicer vehicle and it uses a Ford/Volvo drive train, but interestingly enough, we had one a little while ago where we did a service where both the front and rear differential pinion bearings were worn out, it made a horrible noise when you were driving down the road. It didn’t even have 80,000 km on it, and apparently the rear pinion bearing failure is very common on these. So I don’t know, they’re not built all that well either. That’s all I can say on those, they’re not great vehicles.

Mark: So that’s a pretty scathing review, you normally don’t say that kind of stuff about bad things about vehicles.

Bernie: Really I don’t. I think almost any vehicle you can buy nowadays and even within the last ten years is a good vehicle. But the Freelander really is a piece of crap and I find it frustrating being in a business where we’re trying to fix vehicles and get them going and save people money and yet it feels like with the Freelander no matter what you do it’s a waste of time because it’s just a ticking time bomb. So it’s not really worth our efforts to even work on one.

Mark: So here we go to the dealer, kind of viewpoint perhaps, the Land Rover and Range Rover especially are really fancy, high end vehicles, very expensive, aren’t they best serviced especially at the dealer?

Bernie: Well, the definitely are fancy and sophisticated vehicles, however any shop with proper equipment and skilled technicians can work on them. We’ve invested a lot in equipment to work on Land Rovers and Range Rovers. We’ve got the right diagnostic equipment and the service equipment to do it. Dealers generally do a good job, but we were recently shocked, we had a client who had a two year old Range Rover, 2012, 20,000 km, was quoted $1,200 for service from the dealer. We did the same service for $450 taxes included everything, out the door. And I really can’t figure out what they could have possibly done for $1,200 on a two year old, 20,000 km vehicle. So you know with dealers of the European cars, we often see people with huge quotes for service and I’m not sure what they’re getting. It’s not the case with all of them, but some of them, it’s crazy, I don’t quite understand. So I think there’s the opportunity for us to save, especially people with high end luxury cars a lot of money on their service

Mark: So it sounds like you can save people a lot of money on service

Bernie: Yeah, absolutely in many cases we seem to find that.

Mark: Any final thoughts on Land Rover and Range Rover?

Bernie: Overall they’re great vehicles but they cost a fair bit of money to buy in the first place, but because it’s a luxury vehicle, you can expect to pay more maintenance and repairs. They’re more complex built, there’s more parts to break so that’s going to cost more money. A lot of times they’re a bit exclusive, so you’re stuck with a dealer for parts. And the other area with Land Rovers, that can make them kind of expensive is that somewhere in their servicing and I’ll just leave you with a final example; a transmission service on an LR3 for instance, normally we take the pan off, clean it and put a gasket and filter in and flush it with a machine. The Land Rover uses a synthetic fluid which is not uncommon, it’s more expensive, quite a bit more expensive but lots of cars use synthetic fluid. But with the LR3, the transmission pan is complete assembly of a pan, a gasket and a filter, it’s several hundred dollars for the part, and then labour wise to get it off – it was never really designed to be removed easily, so it’s another couple hundred dollars labour in addition. So it makes for a very expensive transmission service, still worth doing every 100,000 km to keep the transmission alive but that’s just an example of what you do end up paying sometimes to service these vehicles. But overall, great vehicles, a few more problems than some but we can service them and we love working on them.

Mark: Awesome, thanks. So we’ve been talking Land Rovers and Range Rovers with award winning, best in Vancouver for auto service, Mr. Bernie Pawlik of Pawlik Automotive. You can reach them at pawlikautomotive.com a fantastic website with tons of information or give them a call 604-327-7112. Thanks Bernie

Bernie: Thanks Mark, we’ll talk again soon

2008 Land Rover LR2 – Differential Bearing Replacement

Land Rover LR2

Friday’s featured service is Differential Bearing Replacement on a 2008 Land Rover LR2, brought to us by a client from Dunbar, Vancouver.

Land Rover LR2

2008 Land Rover LR2

This Land Rover LR2 came to us with a noise coming from the rear of the vehicle which was noticeable at both low and moderate speeds while driving. Initially we thought the noise to be a bad wheel bearing, however upon further inspection we found the noise was emanating from the rear differential. While diagnosing the vehicle on the hoist we also noted a very loud bearing noise coming from the front power transfer unit as well. This is the name Land Rover uses to describe a type of bevel gear assembly that transfers the front wheel drive motion to the rear of the vehicle.

After breaking the news to our client that both differentials needed repairs we proceeded to remove both units and dismantle them. What we found was interesting: on both units the small pinion bearings were badly worn. This issue is common on the Land Rover LR2 rear differentials as Land Rover has issued a bulletin outlining the repair procedure. All internal parts are readily available.

Front differential or power transfer unit repairs are less common. The only parts sold by Land Rover are the outer seals. Worn bearings require replacing the whole unit at a cost just shy of $1800.00. We dismantled the unit and found only one worn bearing at a cost of $40.00.

After replacing all bearings and seals as required in both units we reinstalled the differentials and took a quiet road test.

Land Rover LR2

Rear Differential Assembly

Besides saving our client well over $1500 on this repair job there are few interesting things to note:

First is that the front power transfer unit is equipped with “fill for life” fluid. In our repair information this is touted as a benefit, and yet at 85,000 kilometers this part has failed. Would changing the fluid more frequently have saved this part? Very likely yes; however based on both bearings in front and rear diffs wearing out it may just be bad engineering that caused these parts to wear.

Second, is that this drivetrain is essentially a Volvo all wheel drive system. Ford, owner of both Land Rover and Volvo in this era share this platform among several models. The front differential failure and lack of individual repair parts for both brands is similar: see our similar blog post about repairs to a Volvo XC70 angle gear unit .

Third, both Volvo and Land Rover sell a very expensive ‘special lubricant’ for their power transfer unit or angle gear unit, yet these components only consist of simple gears and bearings. These units require nothing other than regular gear oil for proper lubrication.  We always use synthetic gear oil just to add a little extra margin of durability. This still costs a fraction of the dealer fluid. It is important to use the manufacturers recommended fluid while the vehicle is under warrant.

On a final note the Land Rover LR2 is known as the Freelander in the rest of the world. This newer generation is a massive improvement over the previous generation with its crappy, unrepairable and frequently failing engine.

2006 Land Rover LR3 – Air Suspension Compressor Replacement

Land Rover LR3

Today’s featured service is Air Suspension Compressor Replacement on a 2006 Land Rover LR3, brought to us by a client from Coquitlam, BC.

Land Rover LR3

2006 Land Rover LR3

Many Land Rovers and all Range Rovers from the past decade have air suspension. This is one of the highest failure systems on these vehicles.

Air suspension is complex, featuring air springs and ride height sensors on each corner of the truck plus an air compressor assembly, control valves, piping, wiring and a computer.

Many Land Rover/Range Rover vehicles experience air suspension system concerns at an early age with failures of ride height sensors and compressors most common. Our featured 2006 Land Rover LR3 had nearly 200,000 kilometers and some hard off road use before its compressor failed: a pretty decent lifespan.

Land Rover LR3s and Range Rover Sports mount the compressor assembly under the vehicle, inboard of the frame in front of the driver’s rear wheel. This is a poor location for such a critical, expensive, electrical part. In Land Rover’s defense they do mount the compressor in a protective box but it is far from weather proof. Late 1990 to early 2000 Range Rovers install their units under hood and HSE models have theirs positioned in the trunk area: both of these are superior locations.

Labour to remove and replace the compressor is not particularly time consuming but the part is pricy.

While air suspension is more complex and adds significant repair costs there are many advantages: ride height adjustablitiy being the biggest. As these vehicles are luxury off-road trucks they ride low and stable for on road use but can gain significant ground clearance for snowy or rough gravel roads.

Land Rover adds some handy preprogrammed driving modes to their vehicles. These presets adjust the suspension height, four wheel drive and traction control systems for sandy terrain, steep hills and other conditions one might encounter.

2006 Range Rover Sport – Front Brake Pad And Rotor Replacement

Range Rover Sport

Front Brake Pad and Rotor Replacement on a 2006 Range Rover Sport is Wednesday’s featured service, brought to us by a client from Surrey, BC.

Range Rover Sport

2006 Range Rover Sport Supercharged

Like all vehicles the Range Rover Sport requires brake service from time to time. While this truck is equipped with very large disc brake rotors and pads, especially on the front where most braking effort is needed, they wear out very quickly. This seems to be a fairly common occurrence on many European luxury sport utility vehicles. Pads and rotors frequently wear out as quickly as 25,000 kilometers on these vehicles. Audi Q7’s and Porsche Cayenne’s have similarly short life spans.

What is perplexing is that these are big brakes and designed to quickly stop these performance vehicles. Normally large brakes also equal long life; perhaps they simply aren’t big enough. There seem to be no long lasting, long life parts available so unfortunately we must live with the status quo.

The Range Rover Sport featured here is the Supercharged model. These are awesome vehicles: luxuriously equipped and very fast. Off road they perform superbly, with air adjustable suspension for increased ground clearance and a sophisticated four wheel drive systems. Unfortunately with a vehicle this nice you likely wouldn’t want to scratch the paint, scrape up the fancy wheels or gouge the expensive low profile tires.

2006 Range Rover Sport with 4.2L Supercharged engine

Most modern vehicles feature some sort of warning system to prevent you from hitting something while parking your vehicle. A major component of the system is the parking sensors: usually four in the front bumper and four in the rear.

Failure of any of these sensors will cause the system to shut down. This was the case with our 2006 Range Rover Sport where one rear sensor had died.

Having a good quality scan tool is essential for us to diagnose this concern quickly and accurately. We found that the right inner rear sensor was not registering. Replacing the sensor brought this useful system back to life.

The Range Rover Sport is a fabulous, luxury SUV. It drives like a car but features the toughness of a truck. With its air suspension system the drive height of the vehicle can be adjusted for various road conditions: normal height for everyday driving or raised height for off road and deep snow. This model comes with a 4.2L supercharged V8 engine which provides very quick acceleration.
