Rear suspension noise/klunk 95 e34 525i

Oh, you mean speed rating below factory installed speed rating. This is same in USA only that the tire shops won't install them for legal liability but if customer were to do this on their own.. they can at their own risk.

The V and Z rated tire quality really varies and what customer really wants. They got them all to cater to all types of customers. Cheapies V/Z tires have extremely hard sidewall and have their own quirks I had a Nexen... long lasting tire but really rough ride... and very noisy at low speed when worn but still quiet at highway speed.

Hhehhehe too true. The Nexens I like are all H16 versions- so are not V or Z rated. I don't drive the car above legal limits so these give a far better ride around town, seem to stick better in all conditions (only my opinion- not a scientific study) and are much cheaper.

Actually after driving a few days on replaced pitman arms, I think they did help some with the noise. The thumping/clunking is less, and seems more of a damped thumping. I think it is now the stiffer winter tires causing the remaining noise. Even so, there are a few small squeaks and rattles to deal with. As you know, the queiter a car becomes, smaller sounds become more obvious. Keeping an old car tight is a tough job.

Just installed 4 new Michelin Primacy mxv4 h rated in stock 205/65rx15. Thunking/clunking is reduced a little more. Next will be to check rear shock mounts, especially the passenger side. Car seems to wander a bit more with these tires. I thinks 33 lbs tire pressure all around is too low.

what shock absorbers do you have in rear?

i have bilstein sport with eibach and the piston inside the shock absorber hits top of the shock at times giving a thumping sound, on the PASSENGER'S side. it damaged the strut mount and i had to replace it.

Boge stock stocks. I may have said this before, but I repalced them along with mounts about 2 years ago. Have about 30,000 miles on them.

there is a cross beam, on the passenger's side extending from the dog bone to the differential. is it possible that the trailing arm hits this beam in your case? part 10 here : RealOEM.com * BMW E34 535i REAR AXLE CARRIER



Also - is anti rattling clip mounted on the brake pad at rear passenger's side?

Thanks, will specifically recheck the arm which attaches to the subframe and dogbones. I replaced the subframe bushings/mounts and pitman arms/aka dogbones. The thumping existed before then. No change after repacment.

[Rustam]

Please do not forget that the sway bar transfering motion to the other side would restrain the wheel from dropping quite as far as it would had both rear wheels been off the ground. Only then it is clear whether the trailing arm is in fact able to contact the diagonal beam.

Also - seems my additional question under the picture was missed - "is the anti rattling clip in place on the brake?"
