Service Action Plan: Miles
The “Death Wobble” Prevention Protocol
Routine fluid changes are not enough for a solid front-axle vehicle like the JK. To prevent the infamous “Death Wobble”, every 10,000 miles you must inspect the following components for play or worn bushings:
- Front Track Bar: Check both the frame-side bracket bolt (125 ft-lbs) and the axle-side bolt (125 ft-lbs).
- Tie Rod Ends & Drag Link: Inspect grease boots for tearing and check for vertical/horizontal play.
- Ball Joints: Jack up the front axle and use a pry bar under the tire to check for vertical movement. Factory plastic-lined ball joints typically fail between 40k-60k miles.
