When i run my car theres this loud rattling noise not like something is loose or anything...and the noise comes on and off..its not constant..and it sounds like its coming from the alternator area...i was thinking about it and is it possible like the bearings or something is f'ed up in the alternator? Its a rebuilt alternator, the stock one went, this one isnt even a year old...but It defintaly sounds like its coming from the alternator or around that area...anything it could possibly be, what can i do to find this damn noise...its annoying me lol Thanks
