I have a 2001 Audi A4 2.8 Quattro.

The problem I am having is when I take off from a stop I am feeling a vibration coming from the back of the car. It only happens when I take off from a stop. Not sure what is it. I had the wheel balance and rotate and still the same problem.

Also, I'm hearing squeaking noise coming from the back while I'm driving, does not matter the road surface. Sometime I hear the squeaking it sometime I don't. If I push down on the trunk while the car is park I can hear the squeaking now. Can anyone point me in a direction of what could be the problem.

Thanks,
Kevin

 

Can you yank the back wheels off and see what kind of shape the shocks are in? i.e. is there any oil/fluid leaking out on to the main shaft? and while you're down there check the control arm(s). I've never replaced the rear control arms but I think it's more or less one upper piece and one lower piece - as opposed to the front arms which have 5 or 6 pieces each side

 

Squeaking is probably bushings or worn shocks. Vibration could be a locked up caliper. 2x on pulling wheels off to check.
