Vibration When Accelerating Or Breaking

[jaycee_w_uk]

Hi, hope someone can help with this!

 

I've got a TDI Galaxy (90 BHP) on P plate. When I'm accelerating I can feel a vibration through the steering wheel between 50 and 70mph approx. If I brake at those speeds I get a severe vibration again through the steering wheel. Cruising at the same speeds is fine with no vibration.

I've swapped the wheels front to rear, balanced the tyres, fitted new front discs and pads, and changed the track rod ball joint ends, but the vibration is still there - any thoughts on what else to check? Its recently gone through an MOT no problem.....

if it was rear wheel drive i would say propshaft could it be a cv joint ?

Check the drive shafts in particular the inner offside CV joint as they have a tendancy to fail.

Hi,

 

Thanks to those that replied to this topic. Looks like it may well be the CV joints at fault. I've decided against tackling it myself so its off to a garage. Will post back with the outcome.

Hi,

 

The problem turned out to be a combination of a worn OS inner trackrod joint and tyres.

 

The tyres were the ones that were on the car when I bought it. They had plenty of tread and were balanced etc but I called in at a tyre dealer I know just on the off chance, he took one look and noticed I had the wrong type of tyres. They were not reinforced. Now I know there is some debate about reinforced tyres but I had them changed anyway in the hope that a)it would cure the problem and b)for peace of mind. This seemed to cure the vibration I felt when accelerating or braking so perhaps it was a tyre out of shape after all(?).

 

The track rod joint was responsible for the severity of the vibration under braking which was much more like the vibration felt when discs are warped.

 

I'm still not entirely convinced about the tyres even though the evidence point to them being the culprits. Still its been running fine now for over two weeks with no re-occurrence. Its a very different car to drive!!

 

Thanks again to those that replied to this post.
