Woohoo another one bites the dust! Same thing happened to me, glad to know Im not the only one who's done this now. And I was in 2HI at the time too... just hope the one on my SS is beefier because eventually I will be doing AWD burnouts and drifting.Well guys, pulled off my belt, and figured i would give a little tug on the pully. Well it poped off, along with the shaft that should be in the pump. Kind of a wimpy looking part if you ask me. What dosn't gm know we all like to do AWD cookies.??
