    Check your belt tensioner or your rear pulley could have a peice of debris stuck in it.

    You also might want to check and see if the pulley's are straight. The bolt could be loose and the pulley is wobbeling. When was the last time you changed the belt?

    Here are some possible causes, any of which could require a close inspection:

    1. The belt has a cut or a piece missing somewhere.
    2. A bearing in one of the pulleys is gone or going.
    3. A pulley is loose because the nut / bolt isn't tight.
    4. A pulley has a dent in it.
    5. The belt is loose or stretched.
    6. Wrong belt, perhaps more so if it was recently replaced.
    7. Oil or some other lubricant has contaminated the belt.
    8. Dirt / debris was mentioned earlier

    I'm sure there are more but I'm also pretty sure if you check out everything
    along those lines you should hit upon it.
