    Could be a belt tensioner that is worn or it may have worn decoupler pulley on the alternator. The Generator Decoupler is a one way clutch ( GENERATOR DECOUPLER 3.3/3.8L ). It is attached to the generator and replaces the standard pulley. It is a non-serviceable item and is to be replaced as an assembly.

    also agree with answer 1, how ever your serp. belt runs a number of different components. check all related items. start with the belt itself(rec. goodyear gatorgrip as replacement).
