NHTSA Complaint #11541661 — 2011 FORD F-350

While traveling down the highway at the speed limit, the truck hit a bump and started to shake violently. I slowed down and pulled over to resecure a freezer that was shook loose. We continued on and when I went to make the next right turn, one of the straps, which was sliced during the death wobble, snapped. The freezer slid and seesawed over a cooler. The corner of the freezer came through the rear window striking my wife in the arm and head. I have brought the truck to multiple shops, replaced steering stabilizer, shock, and tires to no avail.
