Vibration in Rear End
I recently lifted my Jeep, but i am fairly confident that it isn't the issue. I got the xj on jackstands, one side at a time to test each wheel, and put it in drive to see what would happen. My driver side seemed fine, but the passenger side looks to be the source of the vibration. The lugs wont tighten anymore but i can feel/hear some play in that wheel. Any direction would be appreciated.

Plenty of thread on the studs isn't the problem, not enough threads in the lug nut is.
If it is a closed nut (acorn style), the stud can bottom out before it is tight.
If the wheel still seems loose like you say, this is the only way that can be if you tightened the lug nuts.
You could also put some washers on the studs, then put the wheel on over the washers, then install & tighten the lug nuts, and see if it actually gets tight (the wheel, but the lug nut).
If it does, you need shorter studs or different lug nuts...if not, then I am not sure what to tell you.

What did you look at...the stud, or the inside of the nut ??

if someone replaced the studs on that side, they may be longer, and bottom out the nut before it gets tight.
may not be the problem, but based on your 1st post, I'd check it to be sure before going any further.
