Art if you are going to get another housing just sawzall the axle tube around the axle and it will come out of the center section.
Or you could cut the axle end off say 3/4 inch behind the flange and have a new end welded to your current housing , that will save the housing and save the axle .

I haven't seen pictures ... haven't checked this thread at home but your expanding bolts comment scare me , where was the adjuster plate during this ??? hopefully against the back of the axle flange?

Time for a cutting torch and burn the bearing out ... but you need to get the oil out of the center ...
