I'm going to take it to work today and weld up a fixture that bolts to the back side and see if I can press it out. I don't think the lug both threads are large enough to push it out without galling or stripping.

This was obviously designed with no forethought of service, only easy assembly. A slot in the hub for snap ring access would make it a 10minute job. Remove the snap ring, push the whole assembly out, cut the outer bearing race off the hub with a torch, heat the inner and remove. Would be a lot easier to put back together, too. Put snap ring on the hub shaft, press bearing on, install as a unit in the knuckle, install snap ring.
