Does anybody know the part numbers on our SRT for the supercharger pulley, mine is starting to make a racket and am trying to get a replacement. Originally thought water pump was going but now think bearing in supercharger pulley making the noise. If anybody knows of part number, either mercedes or chrysler that would be great or is there an aftermarket place too get this part. Thanks not having much luck up here in Seattle with mercedes dealership, chrysler dealership no help. Any help would be great on numbers or where to find for this problem. Thanks

 

a replacement pulley is very expensive, you most likely just need a new bearing and to change out the sc oil.
