Any updates to this? I have a 2016 Duramax 4x4 with 40k miles. The last 1000 miles it’s got the death wobble if you hit a small bump around 40mph or so. It tracks completely straight at high speed. It’s had an alignment and I checked all the front end parts and everything is tight other that the steering box. The dealer said it’s on me to fix since I’m outside 3/36 I’m pretty irritated that this happened so early. I have a 2.5” rough country and running 33s I’ve had them for 2+ years no issues till now. It also has 2-3” of slop in the steering wheel. Thanks.
