I had the alignment and tires balanced today and had DW on the way home. I loosened the track bar gave the Jeep a shack and then torqued the bolts back down. Holes looked fine bushings looked fine as well. I did go ahead and order new adjustable Tb tonight. Can adjustable disconnect cause it thatís the only thing I have added recently?

Have you done a dry steer test with a helper?

Are you experiencing death wobble, where you are nearly out of control and must come to a stop to get it to quit? Or is it more of a speed sensitive wobble that starts, for example at 42mph and continues through 47mph, and avoiding traveling in those speeds no wobble is present?

It's amazing what you can find, engine off and tires on the ground.
Just feeling each rod end/bushing sometimes you can feel the slop or play, where sometimes you can't visually see it.

You didn't mention anything about having the tires perfectly balanced. Imperfectly balanced tires are the biggest/most common trigger for DW. Even if they were recently balanced not many tire shops will take the time to get them any better than what they consider "good enough" which for the type of solid-axle front-end the TJ has is not good enough.

As far as I can tell they are balanced I donít experience and vibration in the steering wheel. Feels and sounds like normal mud terrains on pavement. then it decides to shake and try to put you in the ditch.

Itís happened at different speeds, slowing down, speeding up doesnít seem to make a difference. I have to come almost to a stop for it to stop shaking.

Iíve replaced almost the entire front end this week except for track bar, and upper control arm bushings and that is planned for this week.

You asked for suggestions, I suggested what is the most common cause of DW. Every instance of DW I have experienced since acquiring my first TJ in 1996 has ultimately been related to imperfect tire balance. Loose components like the track bar can allow DW to occur more easily but imperfect tire balance is the most common root cause by actually powering the oscillations which can build into DW.

10-4 Iím going to try an actual 4x4 place that specializes in off-road/lifted vehicle. Iíll have them check the balance again. Iíve read all you DW comments I can find Iím just not sure how you check tire balance without just taking the shops word that they did there job.

I have the best luck at Discount Tire with balance (Jeep, work truck, wife's car) they always come out perfect.

Everytime I'm at the dealership (for work truck) it comes out with a vibe.

It depends on the tech doing the balance job, not the name of the store. When I had to have my tires balanced 3X in one day before they finally spent enough time to get the tires balanced well enough to get rid of the shimmy that was just shy of DW, it was at a Discount Tire store. The very best balance I have received in years was at a small 4x4 shop with a 50 year old low-tech tire balance machine. The guy running it just knew what he was doing.

Death Wobble Solution

I had the same problem with my 2004 TJ Rubicon. To the point where I thought the Jeep was going to shake itself apart. Had to slow down to 5-10 mph to get it to stop... and would come on without rhyme or reason. Had everything looked at multiple times (front and rear end) and multiple parts replaced and nothing helped. Finally replaced tires... no more wobble.... not once. If your tires are close to needing replacement or are wearing uneven, it would be at the top of my list (from my personal experience).

FYI... Prior to replacing tires, the Jeep had an alignment as well as a four wheel balance at a very reputable shop. Didn't help.

Had the tires balanced again though the problem was gone then bam it strikes again. New track bar and control arms are going on in the morning. Next step will be new rubber I’m thinking I will go with 33x10.5 this time instead of 12.5.

Don't play parts darts. It's expensive.

You need to do the dry steer test.

Didnt find anything in my he dry steer test besides maybe an upper control arm bushing. No play but some rusty dust around the bolt. Bolt is tight. They are part of my build list just getting done sooner than planned.

Had seemingly incurable death wobble on my 2000 TJ. Double Skyjacker steering damper set worked.

No, that just temporarily masked the symptoms, it was no cure. Like placing a bandaid over a melanoma skin cancer. Problem-free TJs don't need even a single steering stabilizer to avoid Death Wobble let alone two!

So an update problem seems to be corrected by new track bar or control arms. The only control arm bushing that looked questionable were the upper, axle side.

I had a loose bolt a few years ago in my control arms and had a nasty wobble coming down a mountain pass. Cinched it back up to the proper torque spec and never has done it again. Sounds like you got it resolved!
