Re: Drivetrain vibration/ clunking only on heavy acceleration/ or from a stop

I am also looking for any other possibilities for the cause of this vibation/ clunking as there sounds like something is hitting the bottom of the car but there are no impact marks to show me where the issue is
From what you have described, it sounds like the driveshaft center bearing has failed. It's a moderately hard job, more time consuming than anything.

I'm assuming you have an E32 (1988-1994)? Have a go at this page:
