When you lift a jeep, even a small amount, it will change the suspension geometry a lot. When I lifted my old wrangler 3 inches and put 33's on it, I got horrible death wobble, when before I didn't have a single thing wrong. The control arm bushings were bad, the track bar bushings were bad, the steering stabilizer was bad, all the things were brought forward with just a small change.
Start with putting it on some good jack stands and a pry bar and check for play in all the joints and bushings, in the control arms and steering. And you really have to pry around. Anything is loose, adjust or replace accordingly. The steering stabilizer should be your last bet, as a proper steering set up, in theory, doesn't need a stabilizer.
