when i did my lift i didnt have the passenger side spring sitting in the cup right and it sat about an inch higher try checking make sure it is seated in there properly

 

look itup it can cause to lean...if you lift over 3 you drill hole beside existing hole or install relocating bracket. or else the axle isnt centered, and it will lean a little...had many friends experience their jeeps leaning after adding spacers to existing 4.5 lift, it can cause it. i just suggested it. so try the suggesting the things everyone else suggested. im just a fool. i made that up. im lol with full leaf packs and coils in buckets correctly the jeep still leaned till i relocated the track bar about an inch.

 

Take a close look at your front coils. make sure they both have the same P/N on them. They could have goofed and gave you uneven sized springs. All people are human.

 

Mine was doing the same thing and it took replacing the leafs out back to fix it. The main leaf on the passenger side was screwed and I noticed it the most in the front passenger side. If everything looks good in the front, I'd be looking into new leaf packs or you could search the JY for a decent pair of packs out of a newer jeep.

 

we will check everything tonight again
