the only thing I can think of, would be to put some duct tape on the end of a socket and wrap teflon tape around it to create a good seal and attempt to drive it into the hole after packing real tight with grease. I can't think of anything else that would work any better.

I also want to add that the pilot bearing removal tool (power built) from the local Schucks store is crap, I paid $50 for it, it has aluminium teeth on it to grab the bearing, it started to bend under force and eventually cracked the aluminium. I think I am going to Autozone and getting a slide hammer, and some grease if that fails.
