On my 38 1/2 ton truck I am trying to remove the windshield wiper motor. It looks like I need to remove the small hub, that the wiper sits on, at the end of the motor shaft but dont see how it comes off. I see what looks like a nut with a slot in the middle but dont know how to hold the shaft to unscrew the nut. Any suggestions on how to remove the wiper motor?
