as promised, I'm back.
I gotta say, handling has been much better. I did replace virtually the ENTIRE suspension though, even the leaf springs, so I can't just credit the bushings... Had everything ripped off, and had the bottom frame rust cleaned up and patched, and the whole thing undercoated for protection, which turned out to be a sollid investment already with all the snow on the roads already this year in PA; Only things I think I didn't replace was the actual sway bar(s), and the lower control arms, (I replaced the lower ball joints and bushings though, just not the arms, but the upper is a single connected piece though, so the uppers got replaced).
in any case, yeah, she drives around great now, like a different truck, but the sway bar bushings do tend to start squeeking, so definitely gotta keep 'em greased up or else it gets pretty annoying pretty quickly.
