Grinding in Reverse

[rifenburg26]

My 2021 1500 5.7 seems to have a strange grinding or rattling noise when in reverse, it does not do it every time and seems to only last a second or two and disappears. Does not seem to matter if im backing up straight or turning. Any idea what could be causing this?

Record it, upload to you-tube and post a link to the video here.

My guess would be the brake rotors rubbing a bit on the pads in the opposite direction.
