Scary shit. I had a death wobble in my '57 CJ-5 last summer. It's crazy how much force is at the steering wheel with mechanical (non-power) steering.

scared the living shit out of me!

The whole event lasted maybe 5 seconds before it smoothed out, but it was 5 seconds of white knuckle terror.

Googling around informs me that improper balancing, or over inflation can be one possible cause. The last time I had the wobble was on my 05 duramax, had 230k miles on it without ever changing a part. Got underneath it and everything on the front end was wore slap ass out. Replaced all tie rods, pitman arm, idler arm, ball joints and the damn thIng is still off.  no more wobble, but can't get the tires aligned right and it vibrates like hell.

Track bar
Have someone get in the car and have them move the wheel left to right and watch all the linkage points. The trackbar attachment points are usually the culprit. The dampener shock on the front was a factory bandaid. It will only mask the issue for a while. .jpg)

I've also had it on a '96 Dodge 2500 4wd - new controls did not solve the problem, neither did new tires, TREs or any other part the dealer thru at it under warranty. Increasing the caster solved the problem - I did it in my driveway after the dealer threw in the towel. |

It can literally be anything.
I had it once a week after I bought a 97 TJ with 100k miles on it. Had driven it around town a bit and never had any issues. One day, driving at ~45mph and the hood is shaking like you describe and swore the front was kind of moving side to side but wasn't sure. I thought somehow the hood straps had come undone. Stopped to check..nothing. Pulled the straps and they were on tight. Couldn't figure it out. 2 days later I had the tires/wheels changed out to 35" tires and we found that there was a bulge on the far inside of one of the front tires. No idea if that caused it, but I've had the Jeep for 2 years now and have never had anything like it happen again. |

If you just had a tire fixed, make sure they tightened the lug nuts good. this will cause wobble and a lot of other issues, like tires coming off.

Meh it's not as bad as it seems, you can let go of your steering wheel in a dw and the jeep will continue down th road straight as an arrow until you slow down. My jeep gets it all the time but I haven't bothered to fix it yet since I drive it only a few miles a week anymore.

The bad tankslapper I had was hauling ass tire broke the ground but when I topped the gear out the tire came back down and the violent slapper ensued with the front end wobble. I remembered to let it go, and was lucky the front end settled out instead of crashing. |

Had that happen in my 2006 F-250 CC. Had the whole family in the truck with and we were doing about 65.
It was violent shaking. I thought the tie rod broke off along with a lot of other things. Took it to a shop and they said all the normal parts that are culprits are worn out. Swapped everything out and added dual dampers. Not a problem since, but I still cringe when I hit uneven/bumpy road on the highway. |

Tie Rods, Ball Joints. A known problem on Chrysler front ends. The geometry is bad to start with and the OEM parts are "sealed" and not greasable. Have yours looked at.

Oh Man, I know what you're talking about.
My 89 Jeep Cherokee had the same issue. Steering stabilizer - which needed grinding to get in; both front wheels balanced, all new front end suspension and a drive shaft check to be sure. Done with it finally. I redid the whole front end and that was it. My left side tire would bounce like nobody's business till I did the front end work. The grinding and installing the stabilizer and suspension parts worked. Cheers! -JC |

Check both bolts frame side and axle side. Probably need changed out maybe even new Trac bar. Check pitman arm bolts. |

Track bar bushings and not enough caster are common causes. And generally worn out suspension components. And tires without stiff enough sidewalls.
