I used an impact and got the nut off but I can't get the pulley off. Do I need a puller or should it just slide off. Thanks

I used an impact wrench and got the nut off. But I can't get the pulley off, do I need a puller or should it just slide off. Thanks

Hmmm, that's weird they have always just slipped off after I took the nut off. Maybe spray some penetrating oil on it. :ies:
