I’ve had this problem for a while now, thought it was my top mounts so replaced them. I’m thinking now it’s possibly my wishbones after I’ve installed powerflex bushes. Is it possible I’ve installed the rear bush the wrong way and that is causing it to make contact with mount? It’s doing my nut in now and want it sorted. The car makes the clunk noise when travelling over uneven ground or potholes. When I try to replicate the noise by pushing down on the suspension I can’t pinpoint where it is coming from. Any ideas?????
