Vibration at 2200rpm

Now that the weather is nicer, putting some miles on. I noticed the car has a vibration from the back end of the car at about 2200 rpm...goes away when revs are higher, and not there below. Does not matter what gear or speed....only rpms. Tires are round, so not storage flat spots to work out. Any ideas before I hand over my checking account to Hans?

Thanks.

PS ash tray is empty.

Bet my money it's the mount too. Mine were pulled out exactly 78k. Bushing was mincemeat!

Me too.60,000 miles was what it took on my 2000S six speed.You will love the difference a new mount makes. Also,no banging in the back when accelerating hard throughout the lower gears!

No need to replace the two rear transaxle mounts. Just replace the front mount and you'll be very happy!
