Hey Steve, did you take that axle off yet? I'm wondering if the bearing is on the axle, like pressed on? If so, it should be able to be pressed off. I'm looking at the parts diagrams, and there isn't an outer bearing listed, however on this site they list both bearings, inner and outer. You might be in luck buddy! Everyone sells the replacement bearing for like $12-$15.

Look down and you'll see two G1 axle bearings. One is called "inner" but the one next to is just says "axle bearing", but if you hold your mouse over the photo a little caption comes up.... "outer axle bearing"...
