Hello All,
I have a 1985 300D Euro. When I accelerate from a dead stop the _______ (drive line???) makes a very heavy thumping vibration. It only does it when you accelerate from about 5-15 MPH and only from a dead (or really close to dead) stop. It seems to do this from all dead stop accelerations and is worse in the morning. In the morning if I get up to speed then remove the foot from the accelerator for a second it seems to stop it most times.
I've read through some of the posts and I'm hearing all sorts of things that could be wrong. I think the leading two are the Tranny Mount being bad or the Driveshaft center bushing/bearing.

Thank you for any imput,
Matt
