Death wobble

Subject beat to death I know but this one is interesting. I have developed a death wobble. Tires are balanced and I had no death wobble the two months between when I lifted and now. Just one day about a week ago. Pow. Death wobble. What happened/changed? Would adj. Rear upper arms help any?

Please describe precisely what you are calling Death Wobble. What is it like, precisely? What makes it start and, more importantly, what do you have to do to make it stop?

Lolz. Y'all crazy. Violent shaking of front end, feels like trac bar and sway bar and everything are about to explode out of my jeep. Any where between 40 and 60 mph. Only way to stop it is to slam the brakes. It is set off from bumps in the road it's not a constant thing like usual where at exactly 47 mph it starts to shake. It has to be set off.

Check all your joints. RC kits are known to fail after only a few months of use which will cause Death wobble.

That's similar to what has happened with my Jeep. It seems the bumps set off a chain reaction.

This happened to my tj too. What set mine off was going 50+, and interstate bridge bumps. I replaced the steering stabilizer and it stopped. But I've heard it could be one thing or a number of things too. My new shock say its recommended to be checked or changed every 12k miles.

Mine was from the front trac bar not being bolted down tightly enough. It was an easy oversight as it looked ok but upon further inspection was not. Try jacking up ur front end and seeing if anything shakes. I had to doublecheck all bolts with a wrench before I found the culprit. And good luck sir. These are no fun.

Before doing anything that costs $$$, do the old front-end check for anything loose or moving that shouldn't be. With the tires on the ground, have a helper repeatedly turn the steering wheel back & forth, back & forth, as you watch everything from the tie rod, drag link, track bar, control arms, etc. for any lateral movement. Especially the passenger-side of the track bar where it bolts to the axle where there should be absolutely zero side-to-side movement.

If everything is tight and nothing is wore out then its ur caster. Drag racers refer to it as exactly that caster wobble. When u lift ur Jeep and stock control arms u are changing ur caster angle. Just my opinion

Anyone can jump in and correct me on this one. I believe that adjustable rear uppers will only help with driveline vibration not front end dw, 99% sure you've got something loose or not aligned.

Adjustable rear upper control arms aren't going to help with DW.

SOMETHING is too loose in the front end and the DW is likely being triggered by a front tire that isn't perfectly balanced. A common object that is often just loose enough to allow DW, once triggered, to fully develop is the passenger-side mount of the track bar. The mounting bolt hole can be wallowed out, the bolt might be too loose, or the bushing inside the track bar at that end might be worn out.

The front axle mount of the trac bar has almost a half inch of play when the steering wheel turns. But it's play in the rubber. Bolts tight sleeve tight just rubber squishing. Everything else is solid.

That's your problem, order a new track bar or play let the bushings on fire and replace it. I'd just replace the trackbar

Called it. I agree with mike. Get an adjustable. Much easier to put on and the best part is no more death wobble! Mine is bds but there are several companies make great ones.

If your budget is decent, go for a JKS or Currie track bar.

I'd stick stock, quite a few threads here on hitting aftermarket diff covers. Could be an issue but once you drill out there is no going back.

A Barnett should work but a new currie hit my riddler.

.....?
Although I do plan on getting a riddler eventually. But the riddler won't contact the stock trac bar as opposed to a jks or currie

Currie hit my riddler solid. Stock bar hit on rare occasion but never hung up like my new currie. Depend on lift, bump stops, angle of axle. Several thread here or jeep forum, Unlimited04 had a lot of research into it.

That said don't go to a new track bar in the front that is non stock without doing to due research!
