I am completely anal about my XJ. Noises, and things like that simply must be tracked down. It's a 96 and had Rustys 3" full leaf kit until recently. The coils had sagged so much and it was not level so I swapped some stuff. Here's the specs now:
Full 3" leafs with Chevy lowering shackles (they actually raise the Cherokee about 2")
RE 3.5 coils and .75" spacer.
Skylacker fixed LCA's.
Track bar relocation bracket.
I guess this stuff raised it up about an inch from where it was and leveled it out. I was really happy with how it sat afterwards. I did get it aligned. I definitely notice it handles differently now though. It seems to require a lot more corrective steering while traveling at highway speeds. I don't think it follows grooves in the road and the steering wheel does not jerk in my hands from bumps. My friends that have 8" lifts and 35-37's tell me to stop being a woos and drive it. They say if it handles differently it's just b/c it's a lifted XJ. This can't be right though. I wonder if the trackbar and draglink angles are screwy or it has something to do with the relocation bracket? I'm hearing a lot of guys say that bracket is garbage and can cause bumpsteer. I'll get a pic of my angles if it will help. I don't think I'd want to drive the thing on a long road trip right now b/c something just doesn't feel right. Thanks.
