Rear clunking when hitting bumps.

Any thoughts on on what would be causing a clunking noise when hitting bumps? Sounds like it’s coming from the rear.

Have tried to track it down some, haven’t checked the control arm, shock, or track bar bolts because I noticed it tonight, but looking for ideas.

I jacked up the rear and kicked the rear tire and heard a slight clunk, but I don’t know if that would be causing me to hear it inside the cab while driving down the road. Only happens when I hit a bump in the road.

Driveshaft, heat shield, control arms, track/sway bar....could be a lot of things. You install anything recently or do any work back there?

Probably a worn out bushing or something loose.

Well….I think I found the culprit…..

As dumb as it sounds…there was a big rock stuck between the exhaust heat shield and the body. Every time I hit a bump, it would jump up and hit the body causing a big clunk. 😂😂 Sometimes it’s the smallest things.

I had a sound in the back like that and it turned out to be be the tailgate. Stock hinges were beginning to fail. Replaced them and all's better.

Of course that wasn't before I spent money on other things first.
