The serpentine belt tensioner can fail; it may become noisy and/or the belt may jump off. Replacement of the failed tensioner will be necessary.

    Belt tensioner is about to fail. Chatter on the belt caused the bearings in the Alternator to fail. There is one more pully that is making noise when the truck is in gear, moving I can hear that there is vibration. Other people outside the vehicle hear it too.
    The transmission contacts had build up on them, the vehicle now has 160K and will be needing a new tranny.
    I am the original owner, it has been a good truck.
