Hey everyone, I've had the clunk noise only appear recently after I had my tail-shaft bearing go. Just kept getting worse. I decided to replace every component in the rear cradle with super pro bushes. Also changed my gearbox mounts too. Picked the car up from the workshop after work, seemed alright for about 20mins. Now the noise has come back. I haven't had a chance to take it back yet though. But I changed my back brake pads today, and whist I was tightening the wheel bolts, the car was rocking back and forth and I could hear the clunking. So I looked under the car and could see the rear diff bolt moving. This was right after I had tightened it up! It had become loose and wasnt sitting flush on the diff bush. Anyway I managed to record it and uploaded it to youtube. Any Ideas how to stop it? Here is the video https://www.youtube.com/watch?v=_qQ-xVnJKSY
