I need to replace mine too - the current Wishbones/Bushes were purchased from DMGRS and need replaced after 2 years - about 2.5 years to date but the o/s BallJoint has been knocking for a while - BallJoint and Rear Bush are Goosed.
My Car is not in daily use at the moment - (when i'm able) I hope to fit better quality parts this time round
