ok i drive an 86 325es and after about 55-60 mph my rear end starts to shake pretty bad. at about 80 mph it shakes like something serious. and when i come up to a stop sign and am rolling to a stop using the brakes i can feel it kinda shifting from side to side in the rear. anyone got any ideas on what it might be or what it might cost to fix?

you wanna start with the small and easy things, like make sure your wheels are balance also you mention that when you use your brakes your rear shakes? i would take it to brake shop or a friend who knows what he is doing have them check out your tires and brakes. does your car have disc brakes in the rear or drum brakes? im sure some one else could probley help you out more them me.

good luck

my car did that before... then i found out my wheel bearing had failed and the only thing holding my cars wheel on was the brake disk riding between my two brake pads.

but its probably just a poorly balanced tire or a warped/dented rim.

or your subframe bushings are all chewed up.

how much did it cost to get your bearing fixed? i had a feeling that might be the problem and was told it would probly be expensive. and for the other questions it has disc brakes in front and back, and i have had the wheels balanced. i am hopin its just shitty tires or just one bad rim.

they were $34/ea at autohausaz.com

i change everything myself, so im not sure how much flatrate is to work on the e30.. i reckon it shouldnt be more then 2-3 hours.
