So after reading for hours i didn't find anything relating to my problem. i just got a 91 with a 4.5 rc lift and 31s. the tires can def use some balancing but the front tires are the prob. When looking at my jeep from the front, it looks bowlegged. I'm also starting to see wear on the inside of both front tires. i guess my question is do you think my front axle is bent at the inner c's? I'm not new to lifted off-road trucks but then again i'm new to Cherokee's and dana30s. Any help would be great. thanks

My guess would be ball joints. does it look like that even when the tires are pointing straight ahead?
don't have a thing to do with camber/toe
they can affect caster, but that is likely not the issue here
If the tires are "bowed" outwards like he said, the lower ball joints are probably toast. Pretty common on XJs that have been lifted for a while and running large tires and offset wheels.

the lift was allready installed whan i got the jeep. and yes when the tires are pointed straight its obvious they are bowed out and wearing the insides of the tires. are the ball joints on a 30 offset? could they be installed wrong? im used to working on 60s with king pins and ball joint 44s. thies are all pretty much straight forward axles but ive never dug into a 30.

it definitely sounds like ball joints, from my experience the uppers will be fine and the lowers will be toast.
They're not offset. Pretty straight forward to get the knuckle off, replacing the ball joints is an entirely different animal. If you've messed with kingpins, these should be a cakewalk.

Installing new 1 3/4" leaf springs tomorrow. I do not need to remove shackle for this correct? Just the ubolts, and the bushing bolts? Also what is the nut that everyone refers to that is welded to frame and snaps? Will I need to worry about that?
If you don't already have one, you'll need a 12 pt 13mm socket for the unit bearing bolts.
I suggest getting it in 1/2" drive and having a 36" breaker bar handy, I've had them be really really stubborn to get out.
Once you unbolt the calipers, and the unit bearings find a deep-well socket and wedge it between one of the u-joint ears of the stub shaft and the axle tube, then turn the steering wheel so it presses the unit bearing out of the knuckle.
When I took my old D30 apart I was able to get the nuts off the ball joints with an adjustable wrench and 3ft length of pipe.
