Shakes and jitters

[alphaXJ]

I have a 92' XJ w/ 3" of lift and serious problems. The Thing shakes like hula girl anytime you get above 45 MPH or so. I shimmies all the time but going over something like a expansion joint sends it into a fit of rage. I've gone through and done everything I can think of. New tie rod w/ all the ends, ball joints, bearings, track bar, new set of adjustable control arms. it has done it with 2 sets of tires both of which were perfectly in balance, When I was in the process of replacing the steering U-joints I t tried it without the front axle shafts, still did it. It will do it with out the front driveline in, although it does seem to subside in 4x4 although it's not completely eliminated. If you take the steering stabilizer out it gets infinitely worse. It's been my excuse to redo the front end and get it ready for some more lift but seriously enough is enough, I would REALLY appreciate any help anyone had on the matter. Thanks in advance

check your rear driveline angles, if there bad try shims, or put on a SYE. dont know what the angles shoule be or how much to shim, i am not that technical, but i've read enough to know what might be causing it. hopefully someone a lot smarter than me can reply and help you out.
