Here is the only pic I've been able to upload of the side that WON'T come out.
Here you can see the adjuster ring: I have tapped it CCW until the inwards facing "teeth" are in contact with the back of the axle flange, and I believe this helps "push" the axle outwards...

If someone thought it was helpful to goop the other side full of silicone, who knows what they might have done on this side.. maybe the grip of silicone is enough to keep me from pulling the !@*&%# thing out?

Since this pic was taken, I knocked the 5 'closure plate' studs out (on the left), and put a spreader bolt between the two flanges to try and separate them... but I couldn't upload that pic.

I'm going to the hardware store.. see ya in a few.
