I had a pulley squeak yesterday and I ran it quick with either and then no belts. Running squeak went away with no alternator belt, but it would still squeak when I turned it off. The only pulley that would squeak by had was the alternator sometimes. And I swapped an old Gatorback for the Gates I was using on the SC path so the turning off squeak went away. The squeak in the alternator seemed to come from the back side. Is it ok to give it a quick shot of WD40 or something like that on the back side?
