The ones you buy should be remanufactured, take a straight edge and see if your belt is in line and not have a spacermissing or incorrectly placed.

I think the bearing/bushing in the Duralast alternator is going out. I replaced the belt and still had a squealing noise(lights and heater fan on) when the throttle was increased. I installed a new alternator from NAPA and Gates XL cogged belt. No noise or issues. Let's see how long this one lasts.
