Ok, you're probably right.  I would find it hard to believe that they wouldn't be heat treated. 
The coating would explain why I don't see any discoloration.

We just need someone with a CNC to make us some hubs from a stronger material.  ;)

Yes, I would definitely change the bearing while there...

I'm going to look at a few hydraulic presses this week.  Seems like the way to go since I'll sure
have many uses for a press in the years to come.

Well then, I'd say you win.  That's a lot of torque!  At what torque rating should we be concerned
with shearing off the axle stub?
