I know this is a major long shot, but you never know. I had to make a fast U-turn off the side of the road yesterday after I missed my turn. There were about 5 big rigs speeding in my direction so I threw it into reverse and backed up fast. As I was doing so, I heard a huge BANG from the rear of the truck. I got out of there and it seemed to drive fine.

About an hour later, I had turned the steering wheel hard to parallel park and heard it again. Nothing seemed out of place, nothing dripping. The sound is as if I backed into concrete post at 40 mph. It's crazy loud.

Ran it a bunch today and nothing seems an issue - steering and suspension seem fine, no rougher ride than usual, no drifting.

I can't think of a reason to take it in to the shop if there's nothing wrong with it, but those noises are NOT normal and I'm worried I'll be on the freeway when whatever it is that possibly went bad decides to break for good.

Anyway, to get to the point - has anyone ever experienced this with their truck before, and if so, what did it turn out to be? Truck has a 12" suspension lift and aftermarket exhaust, if that helps any.
