Does anyone know if there is supposed to be a thrust washer in between the wheel bearing and locknut (see attached pic)?
I did not see one when I disassembled the hub.
There is always such a washer between the bearing and the locknut in my experience.
you want that there to reduce the friction the bearing rides on for the axial loads. The locknut would not be a good surface to do that
im assuming the thrust washer is just the proper shape , thick, and flat at least on one side. It also means the locknut isn’t being rotated into the bearing elements.
The lock washer keys into the spindle so that the spindle nut is isolated from the bearing race and movement of the race doesn't apply substantial loosening force. The race shouldn't be spinning so there's no need for a thrust washer.

maybe im not picturing it right but you would still have a tapered roller bearing up against the locknut without the washer
I could have worded that better. All you need there is the toothed/keyed lock washer to keep rotational forces off the nut. There is no need for any additional thrust washer. The lock washer is necessary though.
My d44 only has the lock washer between nuts. While not the same axle it is the same general design. Never seen reference to a washer between between the bearing and preload nut.

no, the purpose of the thrust washer is to provide a surface for rotating elements to smoothly operate against
Not having it means the lock washer is the edge, which is not good and that would potentially change the designed preload or at least affect it indirectly
I have no pictures of the actual parts to go off of , but the thrust washer's name is significant as it relates to axial loads

That's Retarded(TM).
The race takes the axial load. That's the whole point of the "taper" to the "taper roller bearing"
Just about every automotive spindle ever has something like the lock washer that keys into some feature on the spindle to make it not spin.
OP is a one time poster, not participating, hasnt logged on again, no truck info, no hub info - Manual, Auto ? No idea what partial manual page he posted from?
The Dana 50 TTB and the Dana 60 do not use a thrust washer between the outter wheel bearing and the inner lock nut according to the 1996 FSM. Neither my Dana 50 or 60 had a thrust washer there.
Either way, for future searches. Ill make two posts, one with pics for Manual and Auto Dana 50 TTB and Dana 60 (the hubs outward are the same for both axles). And one with the pages from the 1996 FSM.
Dana 50 TTB disasembled in sequence. Dana 50 Spindle. Manual Hub Locks.
Auto Hub Locks. Wheel nut is flanged.
Various Dana 50 / 60 hub and axle thrust washer pics. Some of the later (late 1996 -1997) Dana 60 do not use the axle shaft thrust washers - That was straight from Dana tech line. - Not to be confused with the OP's original question on bearing thrust washers.
Axle shaft with thrust washers.
LH side - Manual Hub lock nuts and tabbed lock washer.
RH side - Axle shaft thrust washers.
Dana 50 vs Dana 60 Spindle (Ill make a sepreate thread on this for future searches, been meaning to for a while).

This looks like it's from Haynes, for late Dana 50 with automatic hubs.
According to the OP's profile, he has a '93 F250.
That Haynes breakdown is incorrect, it has the wrong nuts for the auto locking hubs. I’m not aware of an early model vs late model D50 TTB either.
They also show a ‘stop screw’ for the steering, which is incorrect - it is cast into the knuckle.
That must be an online manual, I don’t see that in my old paper copy.
Haynes is pretty good about corrections. I contacted them once about something wrong and they said they were going to revise it in the next edition.
The screen shot I posted is from a digital manual. The OP's looks like a paper copy.
I've seen mistakes in Haynes too. They've got the wire colors wrong for my fuel pump relay circuits, for one.
could have went without the being called retarded part, but yes I do see now there was a miscommunication/understanding , so that is on me, but on the surface between the bearing and outer lock nut, I was imagining that you meant the bearing was riding against the lock nut, so without the keyed washer. Which is acting as a thrust washer and race element and the locknut obviously holds it there
