Ok guys, got my jeep on the alignment machine at my new job, that I can check it.. The camber on the passenger side was -.09 in the red.. It has been pulling to the right for quite some time. I decided to take a picture of the spindles..

 

Also, to help my caster go more towards 7.5 degrees, would adjustable upper control arms help? I put 4mm shims in and it only went up to 3 degrees positive..

 

Here is a pic of the driver's side (in green)

Hmmm... After looking at the pictures closer, it looks like the axle or sway bar is shifted to the right.. If you look at the sway bar links, they are not fully together..

 

Any suggestions?

Is my axle bent, I remember tightening down the sway bar links all the way..

 

Thanks

Yikes! You will probably need to buy adjustable control arms. There are cam bolts you can buy for the lower control arms at the axle, but they cost a ridiculous amount at the dealership. Also, it does not look like your axle is drilled for the cam bolts. Buy lower adjustable control arms if the wheels are too far backwards in the wheel arms and upper for too far forward.

The stock lower control arm is 15.75" center to center. A 2" lift should need about a 15.8" length. A 3" lift, 16" length. The stock WJ lower control arm is 16" which should be more than enough for you. I am wondering if something is bent in your setup or if they are measuring it incorrectly.

 

Savvy Offroad makes a set of control arms that should be adjustable down to the range you need. As well, they will not fall apart like the Rough Country arms.

Don't know, but to me your truck looks a little taller than a 2" lift - - Did U do the work? - - - Tires too close to back of wheel well? Pic of front DS looks to me like dif pinion is a little high - - Longer LCAs will help with both - - - Know it's all over, but here 'tis again

Thanks for all the help so far guys! I'm learning a lot. What do I do now since I can't move the passenger LCA anymore? Swap axles or what?

OK - U did the lift - good, one less consideration - - - Pic of dif & front DS no apply since 4mm was added after - New pic showing pinion angle would help - - - U may be finished as far as the caster thing goes - - - Pinion angle should now be close to zero, esp since WJ LCA are 16" IIRC & shims have been added to boot - - - Trucks looking good - - The 31s make the wheel well position look a little skewed to the rear but that's another issue U can tackle after you're satisfied with caster.

Why are the passenger's side shim studs maxed out while the drivers side has plenty of room? Are the studs the same length on both sides? Do you have an equal thickness of shims on both sides? Also, have you figured out how to measure caster on both sides with an angle finder yet?

The passenger's have plenty of shims in there, about 2-3x as much as the driver's.. I have no Idea why, it started this after the lift.. No I have no figured it out yet, haven't had a chance to find a angler finder. Maybe northern?
