This is more common among the older 5 tons with the steering box mounted above
the frame. More than likely you will find a tie rod end about to turn loose.
Check the first one off the steering gearbox first and go from there, the
rebuildable end could be unscrewing in the drag link.

I have had 5 tons do this to the point that I was hurt being thrown around the
cab, the door came open and the windshield cracked.
