Wobble issue....need help pinpointing.

Ok. First of all I did a search and have read til I am blue in the face.

Background. A few months ago I installed a 2.5" OME lift with JKS front and rear adjustable trackbars. A 1 " bodylift, motor mount lift and topped it all off with 33s.

It was my first install but i got it done without TOO much trouble. Everything seemed good with very little wobble.

I recently rotated the tires....had to put it up on jack stands. This allowed everything to relax without the weight of the Jeep resting on the suspension.

I drove it to work and it was wobbling most of the way and really had me worried. I got it home and discovered the lock nut on the JKS adjustable front track bar had worked itself loose. (Probably because i had it on jack stands and let the tension off) I tightened it and it was a NOTICABLE improvement. I now only get wobble from 40-46 mph.

I looked at the rear track bar and that lock nut was loose as well. I took the opportunity to adjust the rear track bar and centered the rear axle perfectly. Tightened everything up and it still wobbles between 40-46 mph.

Any ideas?

I had a similar problem after doing my 4" lift, still driving on 31's at the time. We tightened the front trackbar bolt with a ratchet (twice) but it still had nasty death wobble at speeds of 45+ A mechanic buddy of mine told me he had the same problem and that you need to get that bolt really tight. So we used an impact (be careful not to snap the bolt) and tightened and it basically went away (unless I was going like 60 on a road that was in terrible condition, yet still it wasn't as bad as before). Hopefully that might help. Then again I just got my 33x12.50's tires today and the wobble kinda returned but it may be something different this time for me. Good luck!
