Yeah, it's got good information but the pictures leave something to be desired.
It wouldn't surprise me if the second locknut was added to the heavier duty axles like the 50 TTB and the 60 just as a "beef it up" measure.

i do not trust chiltons or haynes manuals, there are too many mistakes in them for my liking.
i just checked the factory service manual.
and i was rite, and wrong.
the F-150/ bronco D-44 with auto hubs and F-250/F-350 D-50/D-60 with manual hubs use two nuts with the retainer ring.
the D-44 with manual locking hubs only uses one nut.

Thanks for looking into it, Tom.
Both those manuals seem kinda iffy, but they do alright if you're just using them to get you going in the right general direction.
Now, on to the list of problems still to be addressed...

My F150's dana 44 with factory auto hubs most definitely had two lock nuts and a the lock ring.
It's important to torque the nuts properly, especially the inner nut, as the inner nut is what sets preload on the wheel bearing, and the outer nut keeps the inner from loosening, in addition to the lock ring. Too much preload on the wheel bearings will cause them to fail prematurely.

That would make sense, that's what Tom cited from the factory service manual in a previous post.
