Possible Fox non-adj steering stabilizer fail

[smbennett]

I installed the Fox non-adj stabilizer from Agile about a year or so ago. It has been fine, until I experienced 2 severe cases of death wobble this month. Both times, on the highway between 70-75mph and I hit a decent pothole/bump on the right (passenger) front. Roads were clear otherwise. The truck started violently shaking (once bad enough that the rear door open alarm triggered) and lost most of my steering. I was able to drift to the right and get off to the side. I took a peek under both times, and everything looked fine. Started it up, and steered fine immediately after. I climbed under later and double checked all torque settings/tightness and no obvious issues. I popped off the stabilizer and noticed it took almost 2 minutes to rebound from full compression on my bench. I do not think that is normal, and have reached out to Fox to check the spec. Meanwhile, I popped the OEM stabilizer back on as both times felt pretty dangerous - and I have been a lifted Jeep guy in the past

Other than that, the truck is running the F/R Fox 2.0 shock set from Agile - nothing else out of the ordinary in the suspension. No lift.

Anyone experience/validate that a failed stabilizer might act this way ? And would anyone be able to confirm a 2 minute rebound seems excessive ?

I have a steering stabiliser (tough dog). It doesn't rebound. If it did, that would be putting pressure on the steering pump trying to maintain a straight line. The oem stabiliser was slightly pressurised... not sure why.
The death wobble is usually associated with solid front axle setup. It was a known but not common phenomenon with Classic and P38 Range Rovers as well as LR Discovery 1&2.
Failed bushes were sometimes blamed.
The front wheel wobble on supernarket shopping carts provides a clue in that it might be worth getting your caster angles checked to see if they've been affected by the thump from the pothole
