Well I've got another clunk happening now. It's not the front or rear cab mounts. I KNOW what that sounds like. Been dealing with that since July of 19. This new one started yesterday out of the blue. I thought something might be banging around in the bed but I took everything out and it's still doing it. Sounds like track bar bushings when I'm driving but standing outside the truck when my wife moves it, sounds like it's coming from the rear. Anybody have something like this happen? 2019 2500 C/C 4x4 short bed Cummins.
