I've posted this elsewhere, too, but I'm hoping for some advice:

I hear an increasingly loud metal bang from the right rear when I drive on roads with sharp bumps. It's only on the right side, and only over sharp bumps, like expansion joints or medium-sized cracks in the pavement and pot holes. The right rear also feels as though it "hangs up" on these bumps, causing a slight shudder.

Obviously, I'm only able to hear it while driving the car, but I'm guessing it's a suspension bushing. Can anyone explain how I would go about determining which one?
