Again, it will come off with some gentle persuasion.
Just like the regular Bendix hubs, if the cage is well worn, you're gonna lose a couple balls...so plan ahead and do it over a container. It's not the end of the world if they fall out either. If they all fall out in the removal process, it's safe to say the bearing assy needs replaced.
Edited to add: Don't try to pull it straight off or all at once. Treat it like a really tight expensive O-ring you don't want to nick, once the first half is over the ridge, it will plop off.
