Good afternoon,
Jumping right to it. I've been on a witch hunt trying to find a rear end clunk that keeps popping up on my 2015 GMC Sierra RWD with a 4.3L V6. For some reason or another I decided to shake my truck bed back and forth, and got both clunking and even felt some back and forth play when rocking the bed by the tire or wheel. I've been told this is just GM driveline clunk. But I'm not entirely positive. I'll have a video linked. If it doesn't work let me know. It may not even be the issue, but input is appreciated.
