Seriously, I DID have a "rattling screw loose type" sound in my car. It would happen when I stopped. It would happen sometimes on curves. It was driving me crazy. I couldn't think what it could be. Then, one day, when I was vacuuming my car, I happened to hit the button on the passenger's ashtray. Inside was my cigarette lighter, just where I'd put it. The lightbulb went off -- now, I can ingnore it, and not be paranoid.
