My car has developed noticeable looseness and power steer from the rear end. I double checked all fasteners. The car has Spohn 207 LCAs (del sphere on one end), Spohn PR and Spohn TA . It's a 12-bolt diff. I noticed looseness in the del spheres, so the next step is to tighten them. Please send your suggestions on troubleshooting and LCA adjutments to restore rear end tightness. Thanks

 

Might want to check the panhard rod as well. Looseness there can cause the chassis to move from side-to-side, which would seem to have a larger impact on steering than small changes in LCA length due to joint wear.

I don't have the Del-Sphere joints, but as I understand it, you can open them up completely to examine for wear. Not sure if Spohn supplies replacement bushing cups.
