It's amazing what a little heat will do!! In this instance a heat gun on the low setting will probably get the job done in 5 minutes or so.
If you don't have a heat gun...get one! They're not that expensive. And while you're at it. Get a high range heat gun and a low range heat gun.
And while you're buying tools, an infrared temperature gun is very handy to tell how hot you're getting the work piece.
Just an add here, if you're going to replace a wheel bearing, a regular oxy acetylene torch is the way to go. I put the new bearing, in it's packaging in the freezer for a few hours. Then using mine and the infrared gun I get the nose of the bearing carrier up to about 480 degrees F. The bearing just drops in with a nice tinkle to let you know it's at the bottom of the bearing fit.
