Default Serpentine Belt

The serpentine belt keeps jumping over but it doesn't come off. Would this be caused by a pulley going out or something being miss aligned?

yes, one of your pullies is off. remove the belt and wiggle every pulley. see if any of them have play.

Thanks. I believe that it is either the compressor pulley, power steering pulley, or the tensioner pulley. Thanks again D.C.

. Funny thing, (not really though), the alternator pulley is squeeling like the bearings or something and the shaft on the power steering must have a problem because the pulley moves back and forth a little. A parts guy that I know said that is ok as long as it doesn't move more than 1/8". Is this true?

Thanks all!
