Need help! My ride height randomly changes from left to right

[natedilla]

After adding Eibach /Koni /GC coilovers and HD rsms on my e36 m3 I hear rattling from my rear end, clunking from the rear coming out of slow corners and my rear ride height changes from left to right. The difference in height ranges from dead even to an inch lower on the right side. My cars got 150k and all bushing and balljoints are probably original. Would worn RTAB's cause this? Thanks.

Maybe the spring is shifting. 1" is alot. I am sure that it is not the GC parts. Sway bar binding? Very puzzling. A problem in the front can affect rear height as well. Call me if you want.

Thanks for your help! I'll be checking my swaybar mounts and endlinks tomorrow. I may try lifting the car up at the end of the trailing arms with floor jacks (to keep pressure on the springs) while the suspension is uneven so I can remove the wheels to investigate whether the spring is properly seated on the perch. If i cant figure out the problem i'll be putting my stock springs back on to help isolate the problem.

Swaybar mounts and endlinks are fine. Could worn subframe bushing cause this? I have no idea what effect worn subframe bushings have on the car.

This is hard to diagnose without having the car here. It has to be some kind of bind. I just do not know where. Check all suspension components one by one. I would be suprised if someone could answer this correctly other than a lucky random guess.

I cant believe I still havent figured out this problem. Im gonna replace my rtab's in hope that they're the problem.
