Hokay, I just FINALLY got around to addressing this again. For the record, I am doing this work on a 4 post lift and all measurements are referenced to the deck which is level.

Got the car on the lift and put the rear frame (jacking points) on the same amount of wood blocking on each side, wheels off. Wheel lip to deck is identical on both sides, leading me to the conclusion that the body is on the frame reasonably straight.

Going into this, the spring adjustment bolts are drivers side all the way up, passenger side all the way down - this is over a 4" difference side to side and still the driver's side is not at stock ride height.

Disconnected sway bar, no load on either side and is level to a reference on the frame on each side - clearly not bent.

Decided to replace original half shaft u-joints. BTW - Jeg's is about half of Denny's, got all six Spicer coated u-joints for $140, free shipping.

With every thing except the shocks and trailing arms disconnected, spindles hang within 1/4" of each other. The spring does not look too bad unloaded, but I'm still thinking it is the culprit. Any ideas for a test? Planning to call Hyperco Tuesday. Thanks in advance for all the support.
