Please tell me you aren't letting those idiots touch your car??? I understand you're new here, but we aren't blowing smoke up your ****. All you need to do is change that IC pump and your troubles are pretty much gone. Should you swap the SC pulley bearing out? Yeah, and use the upgraded higher RPM one ($20 part). Should you let a dealership that has no clue about your car replace a supercharger? Absofakkinlutely not.

You joined a forum that collectively knows more about this car than any state's worth of Dodge mechanics. Stop wasting your time with them and fix it yourself. We've given you the information, it's up to you if you want to utilize it.
