You might have to be a member to see these pics but some good instruction with pictures that remove the auto hub and replace with Warn manuals. I also have the Warn hubs and are pretty straight forward.

The diagram above looks a little different than mine (maybe a Dana 44 vs. my GM 10 Bolt

). The above picture I posted use all three pieces, regardless if I had auto hub or manual hubs. My Chilton lists it in this order:
From the inside of hub you have
seal
inner wheel bearing
inner race
wheel hub
outer race
outer wheel bearing
adjusting nut (the one with nub) - torque to 50 lbs for manual hubs and then back off 1/6 of turn
- torque to 35 lbs for auto hubs and then back off 3/8 of turn
Ring (locking ring with holes in it, be sure to get the nub in one of the holes)
Locking nut (torqued to 160 lbs)
After all this, then the auto hub or manual hub is installed.
