Death Wobble just started?

Owned my TJ for about two years, never had a problem. Recently I'll be driving and it gets to the threshold of about 50mph and the death wobble starts. Never had this happen before and it was pretty severe.

It now starts happening every time I drive it and get to that 50mph zone.

Any thoughts?

Tread on tires is about 25-30%, Im thinking that may be a cause for it starting to happen.

That happened to my other car it was the alignment.My friend had it happened and it was his stabilizer arms. So could be either or flat spots on the tires but that wouldn't explain why it happens at 50. I wouldn't worry so much about the speed it happens at.

Chances are great that it's related to uneven worn tires. You can try rotating and balancing them but I would just replaced them if you only have 25% tread left.

I would check your tires and have them balanced.

Check your track bar...!! And the more times you allow that to happen, the more parts you will be replacing.

If you have to drive at that speed, try swerving slightly to shift the weight of the vehicle to one side or the other. Do this just before or during the moment of the onset of the wobble. I used to do this and it would allow me to pass through the death wobble zone and continue up to speed.

Obviously this is not a fix, and you should really fix the mechanism that is causing the wobble, but it's a workaround if you must drive it.

Check your track bar, make sure it's not loose. Get new tires if they are badly or unevenly worn.

As water dog said, get it fixed ASAP. The longer it goes on, the higher the chance you have of damaging another part that will contribute.

Also make sure you didn't toss any weights off the wheels.

To check for loose parts, get under it while someone turns the wheel back and forth rapidly and also full lock to full lock. Look, listen, and feel with one or two fingers for any movement/popping. Check both ends of the trackbar, tie rod, drag link, control arms, etc.

Imperfectly balanced tires are a very common trigger for DW, & often the entire cause of DW. Other times imperfectly balanced tires coupled with a loose track bar are the combination that causes DW.

But those aren't the only potential causes of DW, they are probably just the most common.
