If you have a set of sockets, you can use them to press the cups out of the yoke. Select one to use as an anvil that the cup will fit inside, but the yoke around it will be supported and another that's slightly smaller than the cups to punch it out with a hammer. Not the preferred use for sockets, but it will work.
Back in the day, GM had an old filmstrip featuring Primitive Pete abusing tools.
Or you can rent/borrow a ball joint press from most parts stores. That's really the correct way.
