Death Wobble

Hey guys! I own a 2004 jeep wrangler X. I've had the "death wobble" for some time now and have done a few things. I've replaced the shock absorber, checked the U joints and balanced the tires and still have the issue.

Little more info on the wobble. When going about 55 MPH, the shaking will start and get worse and worse until I need to slow down to balance it out. It's worse if I hit a bump going that speed. The weird thing is is that it does not do it in the winter.

Someone had suggested a bushing issue but wanted to get your opinions. If you guys can provide any feedback, that'd be great! Thanks!

As many here have said most of DW issues come in the track bar either worn bushings, loose bolts or enlarged bolt holes. There is a video that goes step by step in checking all the components in the front end I will see if I can find it. Here is a link for all the torque settings knowing that you have a TJ http://project-jk.com/jeep-jk-write-...orque-settings

Check your brakes too. My right front caliper was bad and did the same thing. It didn't give me DW in the winter or at night sometimes. At one point I couldn't do more than 50-55mph.

Replaced the caliper and it stopped completely!

I replaced the bushings in my track bar and bam, no more DW! I have a 97 and bought it a few months ago with everything still being stock. I also added a lift kit, putting JK springs on giving a better drive.

I think I'm going to have to do this next as it's very similar to my issue and replacing the front track bushing did not do it. Every mechanic I talk to says that replacing the caliper won't do it but they also told me the front track bar bushing would definitely stop the DW in which it didn't.

Two questions: What kind of condition is the frame end of your track bar, and what is the condition of the the track bar mounting hole on the axle end?

Not sure. Not much of a mechanic, just know the basics.

Have a friend turn your steering wheel back and forth with the engine off. While the person does this look for movement in your track bar. If there is movement that is the problem.

Then you need to have your mechanic check those two areas. The track bar mounting hole at the axle end can get wallowed out allowing movement there even with a new bushing. The frame end is a ball type joint which can also develop slop. You don't want any play in your track bar. Also have them check tie rod ends for play. Just a little play in any of those parts can add up to pretty signicant wobble.

Thanks man! I just did a ZJ tierod swap, and it made a big difference, but I still have a hint of a wobble @ 45-55. I've also noticed a pull to the right as I break. Worth looking into!!

So I had my track bar replaced along with the bushings but the place forgot to realign it so it didn't fix the issue. Went to sullivan tire and got a realignment. They also found that the track bar was off and needed to be readjusted. Tested it on the highway and no death wobble. Hopefully this permanently fixed it. Thanks for the help all!
