noise coming from rear

[bullittrevor]

Have been hearing it whenever I have the window down, its' a squeak/very light metal on metal noise coming from the rear on I think the drivers side. Only happens when turning or going over a bump/pothole. Anybody else had this? Any ideas?

Possibly a loose brake pad or caliper moving. Next time you hear it, slightly apply the parking brake and see if it goes away.
