squeeking
 

I'm getting a squeeking noise from the drivers rear corner when I go over bumps. I've just replaced my rear shocks. I have BBK springs which are about 9 yrs old. Would it be the springs or the control arms?

Could be control arm bushings, worn spring isolators, torn torque boxes...

I agree with blue00gt, that it could be any one or more of those things.

Look for witness marks (scratches) where metal/metal may be rubbing.

If all else fails, quite literally, empty an entire can of WD40 on that side and see if it cures it. If it does, you are getting warmer... warmer...
