Intermittent reverse scraping/squeak

So I’m backing up, and intermittently (at definite intervals) I hear this scraping metal-on-metal squeak/vibration type noise (hope that makes sense lol). I have no clue what it might be, just wondering if this sounds indicitative of something I’m not aware of. Thanks!

scraping- not sure. does this only happen when in reverse? brake pads worn? brake dust shield touching?

squeaking- rear suspension rubber bushings. do you have suspension upgrades? polyurethane bushings squeak.
