driveline angle (rear driveshaft) on vibration more than likely, as for violent shaking...the most likely culprit is tracbar if your lift used a relocating bracket make sure the bolts are tight and loctite them.

i didnt do anything with the steering. all i did was undo the front sway bar while i was installin my lift and i put it back on. the lift kit was just coils, shocks, and add a leaf.

Well at 3" of lift you need to at least adjust the trackbar or your axle will not be centered. Also when lifting any vehicle every component up front must be in good condition, if not problems will show up real quick. Is the shake more in your seat or the steering wheel?

I have a 4.5" rough country and I haven't had this prob. Dont get a t case drop if you plan on 4 wheeling. Very bad idea. Get a slip yoke eliminator best thing you could do. And back to the vibs, it prolly has to do with the trac bar

I agree, but if money is tight a t-case drop is a temporary fix. A sye is the way to go, unless you like replacing u-joints every 6-8 months which is not much fun. Although I know a bunch of people on here will tell you they run a t-case drop and have never had any issues. Every xj is different I suppose.

That's true but I guess it also depend on if you have a HP or LP rear end. Personally I don't want to move the t case from it's factory spot unless I got a better one that requires some tweaking

did you get it alligned after you did the lift?
you should be able to use the stock tb at only a 3" lift
also did you go full pack or just aal, if did a full pack usually takes a few weeks for the springs to drop down to the 3"

alignment is definately called for if over 1.5 inch lift... but i just had the same problem.. a tc drop is needed.. until u can afford a sye or hack n tap...
go to lowes and get some 1" square tubing. drop the transfer case crossmember. cut a piece of tube to length and drill holes thru . remove the factory stud from the unibody, and bolt the spacer between the frame and crossmember with new grade 5 or better hardware...
