What causes it and how to fix it

 

Many things. Could be trac bars, cam bolts, control arms and angles of driveshafts if you have adjustable CA's and they are not set correctly or tire balance. I would start at making sure all trac bar bolts are torqued to 125ft lbs and then move to CA's. Unbalanced tires can seem like DW if they are not balanced correctly.

Find planmans writeup on it.

 

Take your trackbar off and look at the bolt holes on the brackets to see if they are wallowed out. Most of the time this is the. cause. If that's the case then you need to reinforce them.

 

Fat girls cause it... Kick the fatty out, and you will be impressed how straight that sucker drives

More generically, death wobble can happen to any solid front axel vehicle (as opposed to independent front suspension). It's not just a Jeep thing.

 

x2. Thanks happy thats what I was referring too earlier, couldnt find the link...To the OP, this writeup is accurate enough to the point that I have a printed copy at home with some other jeep service manual crap. Read it.

 

Mine started after a lift. After many changes the ball joints finally fixed it.

 

Damn! I was trying all the fixes and nothing worked. Kicked the heffer out and now it drives straight as an arrow!
