As long as you didn't touch the bearings then the original shims will be fine, otherwise I check them with feeler guages.  The disks shoudn't be causing those symptoms and nor should the CV, my favourite is on the UJ  for now, unless it is the engine (and we don't want it to be).  If the vibration came from the wheels it would also come up through the steering.

Hi again

Its defo engine related and not drive train. I have an Auto and the vibration is at its worse at 2k RPM give or take 100 and nothing like as bad either side of this. Kinda like the vibration in your phone.

Could it be some vibration in the turbo or is it still more likely to be an ignition probelm? I have noticed that it is becoming dificult to start ie. Start and let go the key and then it cuts out and you have to restart it then its fine. I think it even does this when warm.

Can't see why you're saying it's not the UJ in the prop shaft - that's what I'd check and double check.

felix:
Because its an auto the engine speed varies dramaticaly compared to wheel speed. So with the drive train turning at constant revs its possible to vary the engine speed bringing it in and out of the zone that causes the vibration. Its quite noticibly not related to the drive train. It has to be engine problem or back as far as the torque converter.

I am going to change the filter and see if that helps.
