While driving down the road pulling a trailer the steering wheel started to get sloppy it got up to 3 to 4 inches of play in the steering wheel before the wheels return either way the adjustment screw locking nut and clip all came loose and backed out and caused a slap in the steering gearbox the truck became unsafe to drive I had to park the truck until the parts were ordered and the whole gearbox had to be replaced at a cost of over $1500. Gm has service bulletins out there on this problem they all came from one assembly factory but they said they would not repair the truck it was under my expense.
