anyone here experience a rattle from the front of the car while in motion at low or high speeds? I notice when i'm on rougher road and when i go over bumps i hear it. Just took it to dodge and they said come back in the morning ... it doesn't sound really bad and i've never noticed it because i alaways have music on but my g/f noticed it and it was only constant when going down side streets and gravel but I do want to know what this is ? It sounds like plastic rattling.
