Clunking/Knocking sound o/s rear

speedo · Feb 13, 2009

As title suggests i have a rather annoying knocking/clunking sound from the o/s rear? I notice it more when i come off and put on the gas also when i bounce the car up and down (at the o/s rear corner). I have looked at other posts and have checked out the diff mounts and they seem ok. What i have noticed is where the sub-frame attaches to the chassis that there is a small gap between them. The n/s is ok but the o/s there is a gap? I have tried to tighten the bolt to close the gap but the bolt won't budge. Any body else come across this and fixed it or could i be mistaken and its something else?
Thanks in advance for replies.

Could be the nut that holds the crossmember. if you enter knocking sound form rear or something similair you should find past threads that will give advice.

Lots of threads on cracked rear subframe mounting. A common fault.

It is difficult to see the fwd rear diff mount properly to say if it is ok or not. I had same problem and changed the fwd rear diff mount myself, knocking problem was resolved. The side rear diff bushes tend to be ok.
