I have a 2021 Wrangler Sport Unlimited, 6 cylinder EcoDiesel (JL). Installed a 2.5" superlift suspension lift kit + JKS track bar + teraflex lower control arms + Synergy 1.75" wheel spacers a few weeks ago. Still running stock wheels and tires. 30k miles. Took it from Phoenix (AZ) to Moab (UT), went offroading in Moab, no issues. On the way back to Phoenix, experienced severe death wobble out of nowhere. Pulled over, discovered track bar had come completely off (see picture below).
Determined the track bar was defective, returned it and replaced it with a Rock Krawler track bar. Shop made sure everything was tight, checked the torque and alignment, good to go. Same day driving locally - no issues. At highway speed - death wobble returned. Not nearly as violent as the DW when the track bar came off, a more mild shaking that only lasted a few seconds and immediately went away after I slowed down.
Took the jeep to Big O Tires few days ago, they said the front 2 tires were 1/2 ounce off, back 2 tires were 1/4 ounce off. According to Big O Tires, only around 2 ounces or more would cause DW. Tried going over 60 mph after Big O Tires balanced the tires - DW again.
Drove it again today, averaging 50 mph/max 60mph, no issues. talked to the shop again today, thinking maybe the initial severe death wobble caused an issue with the steering stabilizer or something that's not necessarily visible.
Anyone have any experience with this particular issue?
