Ok, if i leave my car in gear... any gear doesnt matter (i usually downshift when coming to a stop)



but when i leave my car and gear and engine brake, when it gets to around 2000 Rmps or under it bounces back and fourth... like i can feel my body move in the seat and i can see the shifter moving forward and backward. it's a pretty voilent motion. what could cause this?



I have new tranny and rear end mounts.. could it be the Drive shaft U joints going bad?

They do have over 210,000 on them. It's really annoying when i have some one else in the car cause the whole car bounces if i leave it in gear under 2000 rpms.



Thanks guys. Markus



P.S It's almost like i'm riding a horse when it does this. It's like Bucking/lurching back and fourth...

 

Bump.
