Death wobble with only a 2" lift would most likely be trackbar play at the mounts, control arm play or worn bushings, axle caster out of alignment, or tie-rod play.
To solve my deathwobble at 7" lift on a 1992 I found these issues:
-Checked control arm bushings for wear and cracking. I ordered new set of adjustable UCAs from ironmanfab4x4.
-Checked to make sure control arms are near to parallel with the ground. I had to order control arm drop brackets from rough country.
-Check trackbar for loose mounts or any play (upper and lower mounts). I ordered a double shear HD trackbar mount and bar from ironrockoffroad.
-Check that axle caster is within spec (May have to order adjustable control arms)
-Stock hollow tie-rod just sucks. I went to the junkyard and pulled a solid V8 ZJ rod.
-Tires were shot. I picked up a set of 32x11.5 BFG ATs at Americas Tire.
-Steering Stabilizer. I went to Schucks and picked up an oversized Rancho bolt-in stabilizer.
I also currently run Bilstein 5100s and I like to believe that they sort of help too.
