I am writing concerning receiver hitch failure on my 2006 chevy 2500 duramax diesel. i have been concerned about this hitches integrity since i purchased the vehicle due to the design. my worries have come to fruition with a near total failure of the oem hitch. i inspect this hitch before every tow and luckily noticed it bending. i have a friend who owns an identical truck who has experienced the same failure. speaking for myself, i have never exceeded the tow rating on this hitch and have never been involved in a situation that caused undue stress. after researching on the internet, there have been numerous failures of this hitch design. gm relies on two bolts running through the bumper for horizontal strength on this hitch. the problem is that the bumper brackets are not designed for horizontal strength and slip approx a half inch. this begins the failure of the hitch as the 2" round tube turns in the receiver brackets due to them being welded on only on side. *tr
