Scotty or anyone please help,
I have a 2017 GMC top-of-the-line Denali that has been clunking since the first couple of months of ownership. The clunk is noise and you can also feel the vehicle surge like it's being bumped from behind. I have attempted either times to get the dealer to correct and they never are able to. So I started making so short videos to show the service department the clunks and still have had no luck.
I have enjoyed your car advice and knowledge for the last few years and was hoping to get a moment of your expertise. Here are a few lvery shory videos I made of the clunks -
Thank you
Larry Singer
I would suspect a loose universal joint or sticking slip joint, or maybe a bad suspension bushing. A noise detection kit like the ones Scotty has demonstrated may help isolate where it's coming from.

Chuck, thanks for the response, how do I get the dealer to do this since this is under warranty and they will not do anything unless I agree to pay their shop time to diagnose?
