The stabilizer is a band-aid. It just masks the real problem, it does not solve it! Start checking for all of the causes, alignment, loose steering or suspension components, tire wear. Fix the problem, don't cover it up.

You may need to look into adjustable control arms if you have a lift. That could have changed the caster angle to much.

Drag link.

I took my unlimited in just before warrenty ran out at 60,000km for a new front driveshaft and steering shock. The dealership also changed out the draglink end attatched to wheel end. It had some movement. I was just starting to get a little vibration in the front end and had the death wobble twice the week before off a couple of bumps around town. I had retorqued everything underneath two weeks prior after installing a full set of TF control arms so nothing was loose. The regular mechanic thats done warrenty work on my Jeep new what to look for.

X2 It may take some work, but something is wrong, and it needs to be fixed.

Don't know if you've done this already, but If you can borrow some wheels off another JK you'll at least be able to rule them out as a cause.

I agree with Phil and jacktuttle... Something is wrong, or it could be a combination of a few little things. Once lifted, all the settings/conditions are just a little more critical. There is essentially less margin for error.

IE, your toe-in is 1/8" too far in, and you have one bolt on your upper control arm 2 revolutions too loose. Strange SLIGHT combinations like this can compound the forces and throw the axle into a DW.

But 9 times out of 10, ok maybe 8 out of 10, it is related to the track bar. I would retork, check for sloppy TRE's/balls, balance wheels, dial in your toe, caster...

Like mentioned above, caster is one of those things that compounds other variables easily. If your axle is too upright, it can make another slight problem bigger. You really are going to need to go through each individual spec, torque, alignment, setting, etc and make sure they are right on the money.

Another thing that further "dials in" your rig is the steering. If you are lifted, you already have steeper angles for you TB and DL... This in itself can be "one strike" against you that can be a mulitplier to another slight problem. Basically, dont necessarily look for ONE thing to be wrong, but make sure EVERY thing is perfect.
