Rear engine mount vibrating
Couldn't find related thread about this issue somewhere (if you have the link, please post) so I'll give a try here. I with VII and changed my rear AYC to LSD few months ago and this noise just happen few month back.
Each time on 1st or 2nd gear slowly turning out from complete stop, I heard a strong vibration sound but the noise goes away after my steering straighten. Brought it to workshop and rectified the problem with my rear gearbox mount, the bushing are torn. The mechanic describe that my rear LSD is locking as I turn my wheel (for example when parking) and causes the gearbox to vibrate. Since the bushing is torned and the mounting could not hold the gearbox, it vibrate and create the noise. He jack up my car by placing the jack below my rear gearbox and the gearbox is like floating without any support.
Well, I found this part no MB990641 from the workshop manual but couldnt find it elsewhere. That part no, suppose is bush replacement part but I can't confirm it. Can someone please help?
