Need help with bearing install

There was a thread on this. Obviously, originally, there was a Chrysler special tool no. C-xxxxx

So use your head. You have some big sockets? If not go to the plumbing store with a new seal, and get a big pipe nipple, cap, or coupling that will span the seal

How 'bout wood bits, you have some large ones? or hole saws? You can cut a hole in a scrap of 2X4 to clear the seal extension.

On the other thread, one guy was going to try PVC pipe fittings. That might work, too.
