If you can get it to Wichita I will fix it for you
EDIT: The biggest cause of death wobble I've seen on stock jeeps is the track bar hole at the axle.
Check out the gap with the bolt in the hole.
If the bracket doesn't hold the bolt still you will get some nasty pops and possibly death wobble. But all things considered you might tell us a little about your rig so we can better assess your problem
