Apparently the Mendeola's violently fast shifts take their toll on parts, here is what I finally found after cutting and beating on the rear hub for a couple hours to get it apart. The freakin' nut that holds it all together had to be cut in two places and I still had to beat both halves off with a hammer and punch!
The wheel flange was completely broken in half so the splined portion was left engaging the stub axle while the whole wheel assy was literally only held in place by the large nut. You can see the broken section with one of the bearing races stuck on the stub axle in the pics.
F'd up part is I spent 2 hrs trying to get that assembly apart without messing up the wheel flange; I expected to reuse it and figured something broke on the stub axle.
Turns out 10 minutes ripping a cutoff wheel into that mess would have been the better alternative.
