Creak / in rear suspension parts?

mweisdorfer · 03-05-2015, 04:32 PM

I have a really nasty creak in the driver's rear of the suspension somewhere. It creaks when I get in or out of the car and when I turn or hit bumps.

I think it might be the rear control arm or also known as the trailing arm. I found a DIY on the upper rear control arm on Pelican but can't find a DIY anywhere on an e90 for the lower rear control arm.

Do these bushings even creak? The ball joint could be the culprit too, but I had my hand on the subframe bushing connected to the rear control arm and felt it vibrate a little as a buddy of mine moved the car up and down with a jack under the pumpkin.

What is very common under there that makes such a distinct and profound
squeak like this?

I pulled up and down and side to side on the rotor, and it feels solid in each direction that I pull on it.

Please Advise.....

I chased that squeak for a while too.

Replaced left and right ball joints. No more squeak.
