This is driving everyone crazy. Three different shops and the dealership
can't figure it out. When I hit a bump at highway speed, the whole truck
starts shacking like a wheel coming off. Has anyone had this trouble
Yes. It's called the "death wobble" (for obvious reasons), and is usually
caused by a worn track bar ball joint, at the frame end. You can verify
this by running the engine, and having someone turn the wheels lock to lock
while you observe the joint. There should be NO movement at all - ANY
movement indicates a worn joint, and is the cause of the shake (the track
bar is what prevents side-to-side movement of the front axle). Repairs
include a new stock bar, a new aftermarket bar (Moog makes one), replacement
joints from Lindstad or Luke's Link, or a replacement bar from DT Profab.
