Having problems with your 2002 Pontiac Grand Prix ?
When starting car/slowing down/steering left or right there is a rattling noise (sounds like a piece of plastic broken off and floating) and also once the windows are rolled up (electronic) if you hold the button down, you can hear the clicking/rattling, kind of like when a screw is tight enough and you keep screwing it in...
Your front drivshafts have cv joints, these have grease in them which quiets them. once the grease dries up they rattle. even more so when turning . you should replace both front cv joints. get rebuilt units to save$$$$
