so i recently put my 3.5 re lift on an i cannot get rid of death wobble.....ive replaced the track bar, ball joints , wheel joints , hub asembelys, an all the tie rods....i get death wobble around 50 mph ....it feels like its moving side to side....i also broke the factory track bar bolt so i replaced it with a grade 8 bolt...it had had very little play in it....my question is does the factory bolt fit snug in the track bar, could that be my problem? i also hear a slight vib under my feet while driving almost sounds like a bad hub asembley at times

What about the tires?
Balanced, inflation, check for belt seperation, etc.

When you changed the unit bearings did you torque the axle nut to 175 ft lbs?

Have you had someone turn the steering wheel lock to lock while your underneath looking for excessive play in the steering? Do you have a solid trac bar?

only movement i got in the steering is the tie rods pivoting while turning lock to lock, i have a soild track bar

Not an expert by any means just trying to help. I have done reading before lifting my xj and they say that control arms, Which I think Rubicon Express comes with on all lifts will cause this. And some say the transfer case lowering thing I have read disputed things about the transfer case. I was told by a guy at the store that most wobble is usually the camber or the caster basically the angle and tilt of the wheel.
