Volkswagen Amarok Problems

This could be caused by any number of things. The engine might be struggling to run smoothly at low revs or small throttle openings, or you might have a fuel supply problem. Perhaps the engine’s idle speed is simply set too low. You might even have a broken or loose exhaust mount that is allowing the exhaust system to flail about at low revs when the engine harmonics set up the vibration to create a harmonic reaction. A broken or worn engine mount can also account for odd vibrations at different engine speeds.

But I’m also wondering if perhaps the problem is not with the engine at all, but something in the transmission. The good news is that your car used a conventional torque-converter automatic rather than the more problematic dual-clutch unit that some VWs used.

In any case, this sounds very much like a warranty problem, so take it back to the dealership and give Volkswagen a fair crack at making it right.

The last decade of dual-cab four-wheel-drive utes have emerged as the tow-vehicles of choice, and you see them everywhere filling roles exactly like the one you have planned. Popular models include the Ford Ranger you’ve nominated, Toyota HiLux, Mazda BT-50, VW Amarok, Mitsubishi Triton, Nissan Navara and Isuzu D-Max. But there are also cheaper alternatives including makes like the South-Korean made Ssangyong and various Chinese brands like LDV and Great Wall.

Just make sure you know exactly how much you need to tow before making a decision as some of the cheaper models don’t have the same outright towing capacity and even if they do, some of them don’t have the engine performance to make towing as easy as it should be. For parts availability, the Toyota would be king in really remote areas, but any of the major brands are pretty well covered in Australia.

Meantime, don’t rule out ute-based wagons such as the Ford Everest, Isuzu MU-X, Mitsubishi Pajero Sport and Toyota Fortuna. These offer better ride comfort when unladen thanks to more sophisticated rear suspensions and most have as much or almost as much towing capacity as their ute brethren.

It sounds like you’re chasing a problem that is a bit elusive. If your initial suspicions were that the centre bearing was worn, what makes you think the rear universal joint is now the problem? You could spend a lot of time and money replacing things that, ultimately, don’t fix the problem.

The best advice is to take the car to a transmission specialist who will be able to diagnose what’s really going on and replace or repair those things. Even if the universal joint is worn out, replacing it can be a bit tricky as you have to maintain the driveshaft’s original alignment to avoid introducing new imbalance dramas into the equation. It’s not, therefore, as straight-forward as it looks on paper.

But don’t rule out a damaged, bent or unbalanced driveshaft as this can also cause the sort of symptoms that a worn universal joint can contribute.

While some cars are known lemons and should be avoided at all costs, the vast majority of cars and utes are okay as second-hand buys provided they’ve been serviced and maintained properly. And that goes for all makes and models, not just the VW Amarok. The point being that a well-maintained Amarok might be fine with 200,000km on board, while a neglected one will be junk by the time it has covered half that distance.

That said, the current crop of modern turbo-diesel dual-cab utes are mostly tuned pretty highly which means that by 200,000km or so, many of them will be showing a bit of wear. This might be most apparent in the intake system, the turbocharger, emission systems, transmissions and many other hard-working parts. Again, it all depends on how they’ve been maintained and how they’ve been used. I’d be budgeting for at least some repairs on an Amarok with that many kilometres under its belt. At which point, of course, it all comes down to the purchase price.

It’s always worth contacting a carmaker’s customer service division in a case like this. I agree that 136,000km is far from a reasonable expected lifespan for a modern more vehicle of any sort. But exactly how Volkswagen Australia will view the matter will depend on the car’s service history and how it was used.

You might have some luck and perhaps financial assistance in getting the Amarok fixed, but VW could also point at the age of the vehicle and the fact that it’s way out of warranty. But, again, if you don’t ask, you’ll never know. Don’t bother pursuing this at a dealership level, either, go straight to head office.

It sounds like there’s not much left to change in terms of belts and pulleys on your vehicle. But did you change the relevant tensioners at the same time? Tensioners run on bearings which can start to seize up over time and kilometres, often contributing a squealing noise that is easily confused with belt-squeal. Also, simply changing the pulley on, say the alternator or the air-con compressor, will not cure the noise if it’s being caused by the alternator or compressor itself.

Other things to check include the correct belt tension and the alignment of the belt (is it running truly between the pulleys, or attempting to run slightly sideways?) Don’t rule out a coolant leak that is getting on to the rubber belt and causing it to squeal.

You need to get this vehicle to a transmission specialist right away. There’s clearly something not right either mechanically or electronically with the gearbox, and continuing to drive it in its wounded state is a big chance to cause more damage than has already been done.

Any vibration in an automatic transmissions suggests either torque converter or internal problems. It may already be too late for your vehicle, and the damage may already be done. But the sooner you get to a specialist, the less expensive, permanent damage will be done.

The refusal to shift from four to two-wheel-drive could be any number of things from an electrical or switching fault to a mechanical failure within the transmission or transfer-case. So that needs to be checked out before you do any more damage to the vehicle.

In fact, the best advice would be to not drive the car any farther at all, because the jerkiness you describe is typical of a part-time all-wheel-drive vehicle that is locked in all-wheel-drive being driven on a normal, or grippy, surface. The need for the inside and outside wheels of a vehicle need to turn at different speeds when cornering, is over-ridden in a car like yours when low-range all-wheel-drive is selected. At which point, what you're feeling is the entire driveline fighting itself and loading up incredible stresses into the axles and differentials. Drive it any distance like that and you'll surely break something mechanical.

You’ll often find a bit of lash (movement) in the driveline of a car, and it’s hard to tell from where it’s originating. What feels like a bit of play in the universal joint can actually be lash in the differential. Ideally, there should be no discernible play in the joint itself.

If in doubt, have it checked out by a professional who will also look for signs of the universal joint deteriorating and give the whole driveline a once-over. It’s not a huge job, and shouldn’t cost too much, but it’s a vital piece of the driveline and a safety issue so don’t neglect it if you think there’s some wear starting to show.

The lifespan of a universal joint is usually directly related to how the vehicle gets used. If you go off-road and really stretch the driveline in terms of axle articulation, or you tow a big load or regularly launch a boat and dunk the rear of your vehicle into salt water, then the lifespan of components like universal joints will be drastically shortened.
