I went back out and crawled under the truck and look over the suspension closely.
The front quad shocks look like they've been in there since the lift was installed - and that's been a while. The lower shock bushings on both pairs are shot, and of course I mentioned early the badly mounted / moved front sway bar had actually damaged the lower shock bodies of the two shocks in front of the axle.
Axle pivot bushings and radius arm bushings look good. I know looks can be deceiving - especially being the truck is 24 years old....but to me it makes since to replace the stuff I know is bad.
So the next suspension piece is going to be front shocks (All four), front sway bar bushings and endlinks and rear sway bar end links / bushings.
I'll go from there.
