Well, I'm not sure about the rear axle, but I'm glad I went to your
Flickr album! You've done a marvelous job, that's a gorgeous car!
I'm more familiar with the later axle, I suspect that the bearing is
what's holding the axle into the housing. You could try sticking the
hub back on, put a nut on the end and bash on the hub with a rubber
mallet or something that won't hurt the hub - maybe a piece of wood and
a larger hammer? This is JUST A GUESS, I'm looking forward to other
replies.
Regards, Tony Drews
