It is most likely your sway bar to chassis bushings.
If you hit the bump equally with both wheels, no noise.
Hit the bump at an angle, noise = sway bar related.
Well, I replaced the rear strut mounts on my car yesterday...much easier job than I had thought it would be. Kudos to e34.535i.sport for his excellent write-up he posted a few weeks back. They didn't look near as bad as his. The loud clunking coming from the rear shelf is gone, but the odd occasional pinging sound is still there. I'm kind of at a loss now on what it could be.
The pinging sound occurs at very low speeds on uneven surfaces when the car body is rocking left to right. I have replaced: strut mounts, subframe bushings, dogbones, and the swaybar links. What's left? I have not done the trailing arms or the differential mount. Could it be them or am I missing something painfully obvious? I'm open to suggestions. Thanks all!

Hey there Zmuff thanks, glad it went well for you. Have you replaced the end links on the sway bar? I changed them and that got rid of some of the noisy germlins from the rear end! (If so check the nutsw are still tight as they can come loose!)...
Excellent suggestion by RallyD, the bushings are on my list of things to do! I'll get round to it one day...
I just recently purchased that whole 16 piece kit, but I think I should wait to install it and get some of those mounts too, because if everything else is new, who knows what will happen - might as well change them, yea?

16 piece kit?
Thanks for the suggestion RallyD. I had recently pulled my swaybars and bushings all the way off for cleaning. They are Racing Dynamics with polyurethane bushings and they would squeak like an old barn door. I used some molybdenum grease and haven't heard a sound since. So I don't believe there is an issue there.
I noticed that both sway bar links did not have metal bushings in each rubber center, so the bolts compressed into the rubber pretty far. Can anyone confirm that there is/is not a bushing? Seems like there ought to be. Could be the culprit. They were installed maybe 18 months ago.

There are ebay seller who sold everything you need to change in a package... for front and back suspension.
The kit is most likely not Lemfoerder.Originally Posted by Jon K
