I have a 2010 g6et and it feels like the rear end is moving around over bumps.
It has new pedders front control blade bushes(bearing/pivot style),pedders front diff support(side) bushes and superpro comfort rear diff bush,all around 2000km old,brand new Monroe shocks.
Theres no knocks or bangs it just feels like its moving around over bumps at times and when cornering sometimes when the road surface is uneven.
Ive been chasing this problem for 6 months,my car just feels unpredictable at times.

Any ideas?
Thanks
