Re: Y61 4.2 Rear knocking noise
Or the upper and lower rubber bushes might be "kaput", so as you go over a bump it has excess movement. You should also feel it on pull off though....

Re: Y61 4.2 Rear knocking noise
One of the rubbers on my rear sway bars disintegrated. The sway bar had a lot of play as a result and any drastic movement, such as going over a speed bump would result in a loud clack sound.
I've also had two of my shocks on different cars develop knocking sounds. It was a major pain to find since the shock tested fine. Could have been the mounting rubbers as well I suppose. Either way, replacing the shocks sorted the problem in these two cases.

Re: Y61 4.2 Rear knocking noise
HI, I have recently replaced coils and shocks OME 2", made no difference, going over speed humps does not make a noise.pgreeff wrote: ↑24 May 2019 09:43 One of the rubbers on my rear sway bars disintegrated.

Re: Y61 4.2 Rear knocking noise
Check the sway bar links to see If any of them are loose. Mine keeps coming loose on the rear passenger side and any articulation results in a loud knocking noise because of the play. Drives me crazy it's fine on the tar but as soon as I go off road it starts.
I need to get new ones next time I'm in SA
