Premature tyre wear on VW Passat TDI 130 - d9ber
Hi,

I would be greatful if one of you good people could answer my query. I have had a VW Passat for nearly 12 months covered just over 10,000 miles and on getting the car serviced at VW independent garriage, was told inside tyre badly worn down to the metal almost on the driver side. Sure enough, when I checked the tyre the metal was beginning to show through from the rim. The other tyre was okay. My question, the garriage told me the tracking was out and my steering isn't totally straight, but when taking the car to a tyre garriage they told me it was more than likely bottom wish bone bushes had gone! I need to sort it out but not sure what is the problem greatful if you could offer any advise on this, all other tyres and one on left are okay and evenly warn.

I can't visualise what you mean. Was the rim of the wheel cutting through the tyre?

If it was the tracking, both tyres would be evenly worn in the same place, but the steering wheel would be likely to be crooked.
The first garage sounds rubbish to me, I wouldn't go there again.
Yes, it sounds like one or more worn joint on the front suspension from hell.
A garage will have to find where it is worn and replace the part/s,
To be honest, I'd just buy the whole 10 peice kit to do the whole of both sides and have the whole lot done. The kits are around £250, other wise you will have to pay labour all over again when other parts need replacing which could only be months away.
Best take it to a good VW specialist, as you need special tools to do the job properly without causing misalignment on reassembly or damage seperating parts.

Sorry Ashok, this isn't true. The tracking can be out on one side only and cause uneven wear on one side only. The other three wheels will allow the car to 'feel' okay and travel straight, whilst the fourth gets dragged sideways.

This doesn't mean tracking is definately the cause. It means this is the first thing to check. Given the car is a Passat tho', also have the suspension checked.

How could this be true?
Imagine a car which is correctly tracked. Both sides of the car are mirrored down an imaginary centre line. The car is in equilibrium. All sideways opposing forces are equal.
Now imagine one track control arm is adjusted so that that wheel no longer tracks the same as it's opposite number,
As soon as the car is driven, that wheel will upset the equilibrium and steer slightly the way it was adjusted, so the driver will turn the wheel slightly to restore equilibrium and the car will then be towing in or out equally but have a crooked steering wheel.
