ugh... I'm no newbie, so please take into considderation that this is more complicated than the "simple" answers.

I have death wobble. Yay!!! Here's the issue.
I have a new Teraflex High-steer kit. Rusty's track bar relocator bracket. Rusty's track bar drop bracket. JKS trac bar. I know how to measure it, and my trac bar / drag link geometry is flawless. I have installed adjustabe ball joints and my camber is 0 degrees.
I have a fully adjustable long arm kit and my caster is set at pos 7 degrees. Steering box is in perfect shape and double braced. Hub bearings are solid.

This thing has been bullet proof up until about 500 miles ago. I can't shake it. I feel like every single componet is as it should be. Something is hiding from me. What is it???? I'M LOOSING MY MIND!!!!

 

didnt say you checked your TRE's, might wanna replace those. also make sure everything is torqued to spec.

heres a good post on all the torque specs and what not

Proper toe-in?
Tires properly balanced?
Equal air pressure in tires?
bent rim?
Tried moving the tires front to back?
Condition of control arm bushings/joints (both ends)?
Equal wheel base measurements on both sides?

 

Ever use fix a flat? Alignment. Unbalanced Tires.

Trac Bar(bushings, mounts), Axle Mounts, Tie Rods, Caster Angle, Control arm bushings, Steering box bolts/spacer, Frame(cracks in frame could make steering box feel loose), Damaged steering stabilizer, Bad ball/u joint, drive shaft not balanced, bad front hub, idler arm.

Check those.

 

Well on my 97 XJ when your going down the road in 2 wheel drive the front axle is still turning.... when I bought my jeep I had a bad DW, and I found it to be the U Joints out at the spindles. It could also be the U Joints on your driveshaft from the case to the axle. I replaced all 4 last fall and haven't had a DW since.

 

Tares are well balanced BFG's on new wheels. The death wobble is caused by hard bumps. The upper control arm mount on the driver side has a little play, but not sloppy. I run 28 PSI in the rubbers.

Umm... I can't think of anything else.

 

Got it. I had an opposing force at work on the back side. I pulled my front axle back 1.5" and pushed my caster up to 0 degrees instead of 7 pos and It drives like a Camry... Haha.

I found a guy in Rainbow City Al that is a jeep Yoda. Probably the smartest steering and suspension guy that I have ever talked to in the terms of geometrically understand the load caused on a suspension by gravity...

 

Hello, sorry to drop in would this guy know about lowering a 2wd XJ?? Need advice and what problems i may run into

 

Hard to say. You can find him online www.frankies4x4.com
