I have a 2016 challenger hellcat I have had it since 2018 bought it with 9k miles on it. I now have 38k mikes on it and my supercharger bearings are squealing I have dropped it off at the dealer to get replaced. I will update as I get more info
My apologies it is warranty work just find out there going to just replace the whole supercharger parts should be here in a weekSince it is a 16 and you did not specify this as warranty work, am wondering what they expect to do specifically on the two bearing sets and what they are charging you when compared to rebuilds from reputable shops like Jokerz who I used or others like FAS or SDG.it is warranty work
