Sagging Demon, Help

Before I rebuilt my suspension I had a similar problem. I can't say for 100% certain, but I though it was due to the completely worn out lower control arm bushing(s). I know the strut rod and t-bar center the lower control arm, but my bushings were almost all gone. Its hard to check them with the arms installed, but with the t-bars out it should be easy to see if there is alot of play in there, also make sure the t-bars are on the correct left and right sides.
