Tap it with a drift and it will fall right off.
Reverse the process to put the new one in; chill the bearing, don't heat the hub; keeps from damaging the dirt shields on shielded bearings.

Well, the bearing (3/4 of it anyway) is already off (so I need not worry about hurting the plastic ball retainers). I actually bought a fancy FWD bearing press tool, with a bunch of different mandrels to remove and replace the bearing. Only one side of the inner race remains, stuck on the neck of the hub, and my intention was to heat the race (not actually the hub, which if anything, like you suggested, I was inclined to chill).
I just don't know what's worse, the cold applied to the hub, or the collateral heat from heating the race to get it off. Bottom line; temperature does shit to metal no matter what.
Not thrilled with the fact that a press fit is all that holds the wheels on the car...but I guess that's the deal.
I hate FWD cars. What a colossal bad idea.
