2018 wrangler jk, 35” tires with 4” lift.
Three weeks ago I had a full inspection done because I have been trying to cure a consistent death wobble. The inspection found that I needed a wheel bearing, ball joints, track bar bushings and there is wear in a couple of the adjustable control arm bushings. So I replaced both front bearings, new HD ball joints, inner axle seals, front u-joints and track bar bushings. I haven’t addressed the control arm bushings yet because I can’t find replacements.
everything has been working amazing since the repairs, until tonight! I hit a pot hole at highway speed and it set off a scary death wobble again. Would the control arm bushings now be the cause?

 

I would start by double-checking torque on those TB bolts. if they are undertorqued even a little bit they can cause issues. 125 ft lbs. Control arm joints are rarely the problem, but I have seen them be a culprit once or twice over the years. In my experience, for a full on wobble, it typically takes 2 issues....either under torqued bolts, bad joints, or combination. Typically with just 1 issue you get some feedback but not a full on wobble. I have trouble thinking control arm joints on an '18 are a problem, but stranger things have happened.

 

im almost at the point of taking the Jeep and trading it in. But I will go through everything again and make sure it’s all torqued correctly.

 

The one other thing that comes to mind is if the TB bracket hole has wallowed out any from previous wobbles. I wouldn't matter if the TB was replaced and torqued to spec if the hole itself was wallowed and allowing movement.

 

that is something I need to address. I have to inspect that again because it could definitely be the issue. I have done the bolt upgrade but the holes could certainly be oval now.
