I've got the replacement hub/bearing units. The old bearing assembly comes off easy enough, but I can't keep the bearing from spinning when I try to break the nut loose.
This is the first vehicle I've owned where the "spindle" was nothing more than a big bolt through the hub.

I'm assuming the spindle bolt and nut need to be re-used in the new hub.

If anyone has any pointers on this it'd be much appreciated.
