I've been having death wobble an awful lot lately and I can't figure it out. The wheels have been balanced, air pressure is the same all the way around, and everything under the front end has been torqued to spec. I have a 4" lift sitting on 35" MT mtz. The only thing I can think of is the front end suspension components, and the track bar is parallel with all other components. Will attach photos when I get off work...

 

I am having the same problem! Gggrrrr

 

I battled this for months!!

Get your ball joints checked!!

 

This was the cause of mine and many other members' death wobble episodes. Do not neglect checking your ball joints. PS: if they are shot, get aftermarket ball joints that are beefy and regreasable; not the factory ones as those are crap.

Aside from ball joints, tighten your trackbar bolts to spec. Also, your draglink and trackbar should be as close to parallel as possible from mounting point to mounting point. If one is at a steeper angle than the other or intersecting the line of parallel than you have at least one of the causes of your DW. Lastly, have someone turn your wheel from 9 o'clock to 3 o'clock while you check your trackbar to see if it is bowing and/or if the mounting bolts are moving in any way. If bowing is occuring then get a beefier trackbar. If the mounting bolts are moving then tighten them to spec and potentially replace them with 7/8" bolts (think that's the slightly fatter size -- someone correct me if I'm wrong)

Take pictures of your components and keep us updated
