Just installed a used set of pulleys I purchased from a member on here. The problem I am having is the rear pulley has a slight wobble. Took it back of and checked all the cushions. With pulley of and a block of wood set hub back in place tapping down with block. Still has a slight wobble. Can't see how it could get bent more like machining off. Any input will be helpful. Maybe they all do some. Never paid attention till now.
