Jeep death wobble

[Michael Forsyth]

I have had my jeep tires replaced and aligned. When I am going 30 + mph, and hit a bump in the road sometimes my jeep goes into a death wobble that is very violent. I have to stop for it to quit shaking. Can anyone give me a possible fix for this.

Mine ended up being my track bar, but that's not the only thing that can cause it. Just ended up being my issue with DW. Bought a heavy duty one to replace the cheap amazon one I put on, but that's what I get for going cheap.

Do a dry steer test first.
A dry steering test is used to diagnose issues like shimmy, wobble, or improper tracking in the front suspension and steering system. It allows you to detect loose joints, worn bushings, or misaligned components without driving the vehicle, making it a safe and effective diagnostic tool.

Step-by-Step Procedure​

1. Park Safely: Ensure the Jeep is on a flat surface with the tires on the ground. This provides resistance needed to detect play in the steering components
2. Engine Off: Keep the engine off (key in RUN position if needed for steering lock) to prevent power steering from masking issues
3. Helper Required: Have a second person turn the steering wheel back and forth from roughly 11 o’clock to 1 o’clock repeatedly
4. Visual Inspection: While the wheel is being turned, observe all front-end joints:
   • Track bar ends
   • Tie rod ends
   • Drag link
   • Pitman arm
   • Steering shaft for immediate response
     Look for side-to-side movement or slop in any joints

Working fine until the tires were replaced and the Jeep was aligned.

Take it back to the shop and tell them to fix it.

Happen to have an alignment sheet?

If you want to fix it then get the tires balanced and get a tape measure to check the alignment.

Here's how to check and adjust your own toe-in that also includes how to center the steering wheel as well as re-center the axle if necessary. With just a little care on your part with nothing more than a tape measure, a big set of pliers, and a wrench, you can easily set your toe-in with as much accuracy as an alignment shop can. Really.

Start after making sure the front axle is properly centered. That may involve adjusting the trackbar's length which can only be done if there's an aftermarket adjustable-length track bar installed. Or if the original OEM track bar is still installed and...
