If it'* not making noise, then it'* fine. But if you want to test it, you take off the belt, then turn the pulley back and forth, there should be no play. If so, the coupler is bad. Look at the snout seal, is it dry? If not, it'* leaking and needs to be replaced. Lift up and down on the pulley, there should be no play, if there is, bearings in the snout are bad. Last check is a bit harder, that'* to remove the supercharger and inspect the coating on the rotors, chipped look indicates the needle bearings are going. I've rebuilt more then I care to remember. If you do need it rebuilt and don't want to do it yourself, you just need to ask.
