Help!!! Vibration on acceleration??

[golde30]

ok guys,
heres my problem, just recently when i was launching my car i heard a thud, and now everytime i accelerate in low RPM's (around 2K), i get vibration for about 500RPM. It feels like the vibration is coming from somewhere in the middle of the car,and not so much from the diff area...the vibration doesnt seem to be present once im in higher RPM's... anyone have any idea what this could be? thanks for any information.

Drive shaft center bearing?

[derek w]

motor, trans, diff and subframe mounts

or

center bearing, flexdisk, u joints

depends what's new and what's not. bad subframe mounts caused a vibration on my 5er

hmm...i havent changed any of those things since i got the car, but the thing is, this problem developed suddenly...i will jack up the car and take a look at the tranny mounts and driveshaft center bearing today and see what they look like. thanks

found the problem..seems that the thud that i heard was my motor falling off the pass side mount, and my fan going into the radiator!! i was racing with my motor like that all nite long...hope i didnt ruin anything else, i also noticed last nite that it was hard to put the car into some gears...im goin to have the car towed to a shop 2m morning. thanks for the info guys...
