Shake
 

2001 cabrio After 10min of driving around 35-40 any gear car has bad shake. Only on acceleration, we you lift its gone. We lifted car and ran at that speed, Cv shafts looked ok but we did hear a noise with with same rythem when you placed your ear by the outer cv boot right wheel like a thumping noise

Note has new tires and I even rotated them to see if I had a bad tire, struts seem fine also
Help

Check the transmission mount.

Have you checked the driveshaft center bearing? I had the same symptoms on an older BMW 635 and this was the cause of the problem.

When my car had it it sounded like something was banging around in the transmission tunnel.
