Every time I acelerate from a stop I hear a creeking sound from the rear of the car, any idea what that might be? I just changed the rear shocks both sets and it's still there.
It's the bushings in the stock lower control arms. They're junk. Squirt some white lithium grease on them. It'll last about 3 months until it creaks again!
EDIT: If you get an O/R mid-pipe, you can't hear it anymore.
