2016 Subaru Forester - Sound from right rear

When driving forward (though not in reverse) I hear a sound from the right rear wheel. It is like a tiny little scrape and it is not consistent but off and on, as though it is cause by a rotation of the wheel. What do you think?

things I would check would be…a stick or something wedge somewhere hitting rotor or rim.

brake sensor on that wheel just starting to hit rotor.

if you just had your rear brakes done. it could be the disc brake backing plate that is a little bent hitting the rotor slightly. or a brake pad shim hitting.

just some thoughts
