Rear suspension noise/klunk 95 e34 525i

[Russell]

Just replaced my beer cans AKA subframe mounts. Handling seems more direct and smoother in corners. Ride seems a little better and more controlled.

However, I still have a 'klunk/thump" which is coming from the rear passsenger side. I thought/hoped the subframe mount replacement would take care of it.

Perhaps my dogbones/pitman arms are worn out again? I did replace them about 125,000 miles ago with Lemforder parts. My rear struts/mounts/bumpstops and springs were replaced about 36,000 miles ago. Rear swaybar links were replaced about 75,000 miles ago.

Any ideas? Search did not reveal anything beyond what I have noted. I need to get under there when temeratures are a bit better.

How many miles on the car? Dogbones are definitely gone by now. Sway bar links are another one and the last suspect would be your control arm bushings... you didn't think this would need to be changed didn't you? They are rubber bushings.

yeah after 125k i'd replace those parts and check the control arms.. and at least check out the sway links. though in my experience the endlinks typically are accompanied by a pop more than a clunk.

225,000 on car and 125,000 on the dogbones. replaced swaybar links alsready.

after listening the noise today I would describe the noise as more of a dull thud. Perhaps it is a rear shock mount. Should not be an issue if the three bolts are not too loose and damaged. Opinion?

could be the inner rubber in the mount

My experience with dogbones is clicking and clunking sound when you are turning fast or go up and down the driveway entrance ramps.

You maybe on the right track for the upper strut mount if it is not OE Boge or something like Meyle HD.

I am hearing it mostly on patches of rough road or rough expansion joints. especially when suspension is rather active.

x2 def upper mount is the first culprit...

WEll, I checked the pitman arms/dogbones with pliers by wiggling them. They were quite loose. The rubber innards appear to worn out. I ordered new lemforders from BMA.
