So I got a 2000 bonneville Ssei n the lady said when the belt broke n pulley came off the super charger the supercharger hasn't worked since she was told the bearings in the super charger are probably bad would it be cheaper to have just the bearings changed or should I just change the whole thing? It just kinda chugs instead of the supercharger kicking in and you can hear a kinda clicking noise coming from the supercharger
