Violent Death Wobble Help!!

It is absolutely terrifying. It happens frequently. I hit a bump in the road..both going straight at higher speeds.. or going slow taking a turn.. the wheel jerks back and forth and it feels like the jeep is bouncing .. so I hit the brakes and usually pull over to compose myself. .. I need advice from you all... not a sales guy. 2008 4dr unl. X . I just bought it. At the auction. Passed the auctions inspection and my mechanics inspection. Post sale is over. Its mine now. I love it but I need it to be safer for my kids or she has to go.

Need to get a reputable Jeep shop to look at it. Probably needs a trackbar and maybe a tie rod. Could also be ball joints.

Welcome to the Forum.

^^^These videos will help you to understand the cause. It’s almost alway track bar caused. The bolts come loose, and the track bar mounting bracket holes, become elongated. You may have other items that are worn out such as ball joints and steering linage, that are also contributing toward your issue.

Also, check the tire balance. I bought a used one as well and in the test drive, it was fine. However, when they prepped it for me they changed the oil and rotated the tires. Just so happened that the rear tires were out of balance and didn't show till they were out front. I replaced the track bar with a beefy one and steering stabilizer and it was still bad. I was extremely upset and could not figure it out. So, I had them rebalanced in a last effort and it was a bit better but they were too far gone. Worn all funky. Then I wanted to go to an AT tire from the MT that was on it. All new tires and it drives great from that day on.

Looking back, I can't believe I drove it for a month with that wobble. It was scary!

3 out of 4 times, it's related to the track bar... Either a bolt not tightened to spec or a bad bushing, etc. But if you aren't in tune with the mechanics of your suspension, take it to a reputable 4x4 shop. If they recommend a steering stabilizer, run fast to another shop...

Here's the typical order of concern.

Advice? Stop driving it and get it fixed.

What part of the country are you in? Someone here can almost certainly point you in the direction of a quality shop to look at it... and more importantly, look the whole vehicle over for other issues. Trust me, the auction made sure it met the criteria of your states legal requirements, not a full safety inspection.

Since you are aware of the problem, slow down for triggers such as RR tracks, chuck holes etc.

We used to add steering stabilizers to old 4x4's before they were OEM to stop the DW. I'd start with the least expensive part and throw money at it till it was fixed, or I was broke

Increasing the caster fixed my "shopping cart". My caster is at +5.

If you throw money at a new part and that's not the fix the DW will continue to degrade the other parts and trash all the new parts/money you're throwing at it. Look at trackbar bolt first and go from there. If it were me, and I was certain I got a good deal on the rig at auction, I'd put my efforts into finding a good off road/Jeep shop and hand them the keys. ESPECIALLY if i knew my kids were gonna be in the rig.
