No more Death Wobble
Check this out... According to an article:
There are two schools when it comes to alignment. Too much caster and too much toe-in can induce death wobble. Too little caster and too much toe-out can cause wandering. Identify your symptom. If the tires start oscillating and hopping violently, you've got death wobble. Increasing the toe setting to as much as 3/8-inch toe-out (yes, readers toe-out; no misprint) has been known to help, or if possible, dialing the caster back to 3-4 degrees positive (bottom ball joint in front of top). The larger your tires, the less caster you should need.

The best part of that article is the opening statement:
"Despite what most optimistic off-roaders try to tell themselves, the brutal truth is that almost every modification you do to your Jeep will have some negative drawback."
The same holds true for some of the fixes that we come up with to solve the initial problems we created with mods.
The suspension. steering and driveline are designed as integrated systems at the factory and some modifications alter the balance of this integration.
Negative Toe may or may not help DW, but combined with positive Caster will increase wheel scrub and hence tire wear.
