07 JKU Death Wobble

Just bought an 07 JKU a couple months ago. I was driving on the highway doing about 60-65 when I hit death wobble. As awesome as this was I am debating on just dealing with it until I can lift it this summer (2.5in Rubicon Express). Should I even worry about it or just wait til I can buy the lift and install a new adj. track bar and maybe lower CA?

You probably need to deal with it now. Installing a lift may not even address the underlying problem. I won't even begin to go into what the actual cause might be, but it's a problem that needs to be fixed.

I have the same issue with my 07 JKU, my question is, should I take it to a dealer? Do you think they would have experience with death wobble and be able to fix the issue without replacing everything in the front end?

If the dealer/mechanic tells you first off, you need a new steering stabilizer shock or WORSE yet 2. <run. a wack a mole attempt. Since a well set up and balanced-tired Jeep dont even need it.

Unless per chance the lift replaced a component that was the cause of it. Lifting it will only make it worse. Since most cheep lifts people get do nothing for lose of caster angle.

Death wobble in your situation is most likely caused by loose or worn trackbar bushings, trackbar bolts, or an enlarged hole in your trackbar bracket(s) from loose hardware.
With the jeep on the ground remove the trackbar hardware to inspect for an enlarged hole in the bracket. If it is normal and round, replace the hardware with 9/16" grade 8 bolt and nut, tighten your hardware to factory spec 125lb/ft.
Do not wait to do this, severe death wobble can cause loss of control, excessive/ accelerated wear of other parts.
If the trackbar checks out ok inspect your ball joints for wear. You can then move to unit bearings. This is all predicated on the fact that your tires are properly rotated, inflated, and balanced.

Are you sure it was a death wobble. My death wobble in XJ was around 40 miles an hour. I was like old my god I am going to died, did not say awesome, said oh xxxx. The Jeep shake violently to point I had no real control of the Jeep, I had to let off the gas to get in control....

Awesome is probably sarcasm, but it is always tough to tell over the internet whether it is actually has a death wobble or not. Every wobble is not a death wobble. Until you've experienced a proper death wobble, it's tough to know the difference. 65 is pretty fast for a death wobble, but great range for tire imbalance

On my '07, I did this. Replaced the stabilizer, it was bad. Installed a steering box reenforcement, which gave me a new track bar mount. And lastly, replaced all of the fully threaded undersized bolts with the proper size grade 8 shoulder bolts. Haven't had DW since.
