Having been frustrated at trying to remove the rear diagonal arm bushes with the subframe in situ I realised the new "clanging" noise from the rear on right hand corners was getting worse and beginning to occur at low traffic speeds.
I believe that it is a C-V joint breaking up and allowing the shaft to hit the metal shroud of the joint.
As I had already removed and rebooted the joints on the right rear shaft I have decided I will try for a permanent rear end repair and replace the lot -...
