the thing is with my car i tried that, the bolt just loosened up. i just loosened the hub itself to where the screw was halfway in and used a meaty pair of vicegrips. i made them tight enough to where i could hardly squeeze them together. then just pushed down. you have to watch them though cause they will hit the head. so you have to push them to the left around the bolt to get the pulley to go down all the way. thats how i got mine and it works every time. you also don't have to worry about BUSTED KNUCKLES!!
