The 3/4 and 1 ton rear axle section of the service manual also covers rear hub bearing R&R (page 4-11 in the 47-51 edition). 1-1/2 and 2-ton axle rear hub bearings are covered on page 4-22 those should be the same as on the 2-speed axle. It looks like there's a snap ring retainer for the outer bearing race.
I'd guess that the inner bearing, race and seal could be removed with a slide hammer puller.
As far as the notched bearing nut, you can get those off with a hammer and drift, but should have the special tool to reinstall them as it's kinda hard to get to the proper torque with a hammer and drift.
