Hi, i traded my EL Wagon on a BA 2 sedan about 3 months ago. It seems to have a rattle/clunk in the right rear when going over some bumps. Sounds like a loose shocker but had it checked and were all ok. The sway bar bushes were replaced but still has the clunk. Only done 100,000k but rear is noisier than my old wagon !! Put it over the pit at work but nothing seems loose or looks loose.

Have a good look at the backing plates. I've seen cases of the small bolts coming loose causing them to rattle.

Upper rear control arm outer bush, they are known to be a problem. Some mechanics call them a "ROSE" joint.
