Fix for rear suspension knocking noise
I've just resolved a similar issue on a 2004 70k miles R53.
When going over bumps, increasingly loud (over several months) clocking noise from rear off side (UK driver side).
I was convinced initially that it was the shock absorber top bush. I ordered some of these but as soon as I removed the shock absorber, I could see the bush was in good condition. Replaced it anyway.
I was equally convinced that it was the trailing arm bush. I ordered some of these but as soon as I removed the bush mounting, I could see the bush was in good condition. Didn't replace this as it really needs a press.
Whilst reassembling, I noticed that the shock absorber bottom bush (i.e. the one with the whole of the weight of the car on it) mounting hole was off centre. I clamped this in a vice and turned it around 180 degrees. Noise has gone away!
I'm not sure that you can get a new bush for this so a replacement shock absorber required soon.
Hope this helps.
