Death Wobble

[BombshellJT]

I have a 2015 JK with about 75k miles and started having bad steering issues a few months ago. Not death wobble, but the steering was so loose it didn't feel safe at highway speeds. Replaced the entire steering setup with Synergy. Tie rod, drag link, track bar, and added track bar/sector shaft brace and a Fox TS steer stabilizer. It's better now.

I'm still running stock control arms, but I'm buying Rock Krawler control arms right now in anticipation of going to a 3" lift. My ball joints are only about 25k miles old as well.

Luckily, I have not had to deal with this with the JT yet BUT... I dealt with it for months with my JK. I had around 70k miles on the jeep when I started having issues. I started with ball joints, then to track bar, steering stabilizer, shock bushings.... ended up being my lower control arm bushings were bad. Replaced the lower control arms all together and bye bye death wobble.

I have a 2020 JT and have been chasing a death wobble problem ever since going from a 2" spacer lift to a 3" Rancho lift. Originally got the wrong part for the new steer stabilizer, so ran without one for a few weeks. Noticed a bad death wobble stemming from bump-steer. Installed a Fox 2.0 through shaft stabilizer, track bar relocation bracket, and flipped drag link at the same time. Wobble still present. Replaced crappy Rancho track bar with SteerSmarts. Bump-steer definitely better but problem still exists. Noticed when removing Rancho track bar the jam nut keeps coming loose, so the axle end was just flopping around. Steering geometry looks great now. Front axle is very centered. Not so much with the rear because factory track bar (replacing with adjustable rear track bar next to center up the rear axle).

But there is still significant bump-steer. At this point I'm not sure what could be causing it.

Did you ever find your root cause.or get it fixed? I have a 21 Mojave with pretty much an all new front end and I just got a pretty bad episode of death wobble today.
