2018 Wrangler JL Death Wobble after lift kit install

0

Hey everyone, I'm really struggling with my 2018 Jeep Wrangler JL Rubicon. I recently had a 2.5-inch lift kit installed, and now I'm experiencing what feels like the dreaded "death wobble" at highway speeds. The steering wheel shakes violently, and it feels incredibly unsafe.

It usually happens around 50-60 mph, especially after hitting a bump. I have to slow down significantly to get it to stop. I've had the alignment checked, but the issue persists.

What could be causing this? Are there specific components I should be looking at? Any advice from others who've dealt with this would be greatly appreciated. Thanks!

Summary: For 2018 Wrangler JL Death Wobble after lift kit install, work through these steps on your 2016+ vehicle:

  1. Confirm the symptom — note when it happens (cold start, highway, after fuel fill, etc.).
  2. Scan codes — save all pending/stored DTCs; don't clear until you've recorded them.
  3. Check TSBs & recalls — look up your VIN for open campaigns and known fixes.
  4. Inspect the obvious — related fuses, connectors, fluid level, and recent repairs.
  5. Test the common fix — follow model-specific service procedures; one change at a time.
  6. Escalate if needed — burning smell, no brakes, overheating, or stalling in traffic → shop visit.
