Rear structure

[Waterloo]

Earnie, I would follow that advice in the link Rawze provided. Those were the items I replaced at around the same 700,000 miles on my truck. That is when about all of them failed, so it would be a good idea to be proactive on the maintenance. It will save you many headaches down the line, and you can chose how to go about it, not be at the mercy of "The Hook" and the repair shop you are towed too.
