Yj Death Wobble - Just Bad Stearing Stabilizer?

I've got a '93 YJ with a case of death wobble. Happens at about 30-35 mph and is always initialized by rough roads. I've got a 4" RC lift and 33" tires.

I jacked it up and looked real close at all the components. Couldn't find play in tie rod ends, couldn't find play in track bar, couldn't find play in steering box, all U-bolt nuts were tight. When jacked up I couldn't find any play in the tires when I try to wiggle the top and bottom (this suggests to me that my ball joints and unit bearings are at least not the problem). I did notice that I could easily move the tires in the steering rotation direction BUT the rotation moved through the whole system, steering both tires, moving my pitman arm, and moving up the steering shaft. I couldn't find any independent play between any of the components. I have manual steering.

This suggests to me that my only problem is a shot steering stabilizer. It's dang old and seems to be covered in oil. Everywhere I read people say that fixing the stabilizer only masks other problems, but I swear everything else looks perfectly tight. Am I missing something?

Get rid of trac bar. As in take it off and never look back at it. And if the dampener is bad change it. Then report back.

Will do about the track bar and the stabilizer. I've been intending to pull the track bar for a long time now. In the back of my head though I have to wonder what would happen in the rare chance that I'm involved in a major accident, my fault or not, and someone points out that my vehicle has a component removed that is supposed to prevent unwanted motion of the steering axle.

You are grasping at straws. If that was the case ANY mod you do could be a considerations for wrecking in court.
Besides thats why you carry Liability insurance...

Steering stabilizers hide steering issues. A good, tight steering setup should be able to track down the road just fine without one.

loose the track bar, gain the working stabilizer. I would assume that this drove correctly and then changed? I would check toe in for the heck of it. If you had enough caster before it really shouldn't have changed so no sense in checking it. DId you check your spring bushings? I have a CJ buddy that's rig goes nuts if these have play.
