River I've been fighting dw on my heep for the last few years and after replacing everything but the steering box itself I can still feel it wanting to wobble. I've welded in extra steering brace, replaced the entire steering link setup and I can still "feel" it wanting to wobble. It did wobble until I replaced the tires last week. A tire wobble will only show the wobble that is available somewhere else. Next stop is the steering box itself. The fact remains that If all components are tight it just simply can not wobble. Now according to your video there was some slop on your TB, the debate about the steering stabilizer is that it won't cure problems, only mask them. any slack in the TB would be masked by a new steering stabilizer until it broke in. Balance tires, tighten tb, check ball joints, and watch for slack in the steering box itself. Following all of those things, loose control arm bushings can also come into play. If all of these things are OK then the jeep simply cannot wobble if the frame is still intact. Start with the wheels and work yourself back.
Bad wheel balance wont' cause a wobble unless something else is allowing it to continue. I believe that counts for any factor. It requires more than one factor to initiate and continue death wobble. The most common initiating factor is wheel balance, the most common continuing factor is trac bar slop.
My trac bar is tight, but my steering was loose. and my frame was cracked between steering box and trac bar mount. I replaced my steering and trac bar and it quit wobbling for a while. Then it started again. I tightened my steering and I stopped for a while but I could still feel it wanting to wobble, It eventually started again. I welded my frame and re tightened everything but It still wobbled. I replaced my tires and had a new balance and it no longer wobbles, but I can still feel it wanting to. all it's waiting for is the initiation. I can feel slack in the steering and the only thing left is steering box. Once everything else is tight and there is no visible play, look for play in the steering box itself.
