Death wobble is the uncontrolled oscillation of the front axle.

First place to start is the trackbar. Make sure the bushing at the axle end is in good shape, mount hole not wallowed out, torqued properly. Joint at the frame needs to be in good shape. Any part that locates the axle can contribute and cause death wobble.

Anyone who mentions a steering stabilizer, tires, alignment, brakes or wheel bearings needs to think about the logic behind their argument.

Mine was terrible. Would start shaking the whole rig at 25. Ended up being the track bar bolt holes on the axle were wallered out. Advanced auto has a moog bushing with a 7/16 sleeve. Had to drill out the hole and buy a grade 8 bolt to replace. Works good now.

You cant honestly say a steering stabiizer wont cause a hard vibration or wobble if it has gone bad. Mine went bad on my first ZJ and it would cause an uncontrollable wobble on country roads. Once I replaced it the problem ceased to exist.

Then you have other hidden issues. All the SS does is mask/hide the real issue. You don't even need a steering stabilizer if your steering is set up correctly. There are some on there that don't even have one. All it does is make things smoother.

^ Exactly.

I don't have a stabilizer and I have no death wobble, no shaking and it tracks straight on the road even with my hand off the wheel and 12.5" wide tires.

I'm going to start out with the trackbar bushing.... if my steering box was messed would it be leaking power steering fluid? Fluid level for that is good, just curious if it could still be messed up causing the death wobble.

Just because a steering box doesn't leak doesn't mean that it can't have play in it
