After 10 months and only 4,000 miles, my 2020 Gladiator went into a death wobble twice in the same day. I was on interstate 295 , going with the flow, and crossing an expansion joint onto a normal interstatenbridge into a curve, the wheels and steering wheel began to vibrate and shake at an alarming rate. The death wobble shake worsened and I immediately began to decelerate, brake and switch lanes to the right to get to the shoulder. It stopped shaking when I rolled to a stop. That same day, on the return trip in the opposite direction, the same death wobble, extreme steering and wheel shaking developed again as I crossed the expansion joint onto the bridge into a curve. Yesterday, I took my Gladiator to the same spot, with my wife taking video, and sure enough, the death wobble began again on crossing onto the road bridge expansion joint going into a slight curve. Got it on video. Took the Jeep to the dealer today for a look see. They report That steering components are not loose but that there is a TSB calling for replacing the steering dampener, which has been ordered for install in a few days. Has Anybody else had this happen? I have made no modifications, no lift, no bigger tires. All stock. Anybody have a copy of the steering dampener TSB? The dealer said that some dampeners may have been installed without priming, and this is what happens. I am looking for any solid information you might have regarding this problem, and the fix. Thanks.
