Alignment was done by yours truly(with a 2x4 and a steady eyeball... <img src="/forums/images/graemlins/rolleyes.gif" alt="" />) I do know that this is an issue.

TRE's are all GM one ton and brand new (less than 2k miles anyways, checked last time I was under)

I did not move the spring perches on the axle. When I did the sas I mounted on the outside of the frame to keep in line. Mounts are super sturday and gusseted. I do know that bushings need to be redone, and I will be putting new u bolts and spring plates as well. I really think once I get the alignment done and the new bushings, this will help ALOT. Thanks for the input. Keep you posted. BTW, I pick up my new project next month... <img src="/forums/images/graemlins/wink.gif" alt="" />
