Even after soaking the end of the shaft in Liquid Wrench and PB Blaster, the shaft refuses to turn in the bearing. The biggest problem I’ve found is that there isn’t a good way to get ahold of the shaft to try and break it loose from the bearing.

I’ve managed to force the shaft and stuck bearing out of the housing with a hammer, screwdriver, and a large bolt. Much to my father-in-law’s chagrin, I did manage to botch up the end of the shaft. Thankfully, it wasn’t too badly, so I should be able to file down the damage. Now to soak it more thoroughly in PB Blaster.
