Try using a mallet and tapping the yoke, opposite of rotation. You may have twisted splines on the shaft... Seen that a few times.

Mine has a center cap on the yolk, if yours has one pop it out and use a gear puller. Maybe try a few drops of marvels mystery oil.

Could we  heat shaft a  little....just enough to break it free?
