My method is to take the old bearing and if possible, disassemble it however you can: (lever the seals off, smash the metal retainer through with a flat screwdriver, then twist it out with pliers, pull the balls to one side and separate the rings. It's not hard).

If you can manage to get the outer ring separated, and you have a bench grinder, you can grind the outer diameter of the outer ring down slightly (keep a cup of water nearby for quenching).

This just takes a few minutes and gives you have a dandy tool you can keep, to install new bearings of the same size later. Since the outer surface has been ground smaller, it won't stick inside the hub, but you can hammer on it all you want, using it to drive the new bearing in evenly.

This method works pretty well for wheel bearings, many steering head bearings, and even fork seals.


I just use a bearing driver.
