Heck ya. We are always up in the Owyhess, camp'n, shoot'n, off-grid training for the kids.
That brown 788 is all over ebay. niiiice.
Yes, these are pink now and who knows what they say. They work.. just have to turn them all the way around and they look like they've been through a meat grinder. I just see them all over the JY and keep think'n I could just swap them for a 1/4ish turn / nice shiny ones. I do like your red ones. Also the outside 'chrome' bit on mine is all jacked looking.

 

Yeah, those are the standard Warn hubs. Could be Warn aftermarket, in which case they're the #9790 part number and would have said "Warn" on the label in the center. But should also be 1/4 turn models.
Yours could be the Factory version Warn made for Ford. I just assumed they were quarter-turn units too, but have never actually turned one in anger. Maybe someone who has the factory version can let us know how far they turn.

If a factory part it would have said FORD in the center instead of WARN. Starting in '80 or so, but some say '79, Warn became the OE supplier. Maybe Bill can fill in the details (if he hasn't already here somewhere?) on when they started in use. I've seen them on newer trucks, but I've never personally seen a '79 with anything but Spicer hubs. Maybe it was a late-'79 addition?
Just out of curiosity, what month was yours built in? Short of decoding the VIN of course, if you have the door pillar decal it should be printed on it.

O cool info. Ya looks like May'79.
Wonder if just the outside hub part is needed or, since going from almost full turn to 1/4ish turn I'd need to get other bits behind it.

 

The Warn branded stuff at least is interchangeable. The **** is what makes it a 1/4 or 3/4 turn hub. The locking mechanism is the same between the #9790 and the #20990 models.
Whether they made any changes for the OE products, I do not know. I kind of doubt it, but have learned to never rule anything out.

With luck though, any Warn or Ford actuating **** and chrome surround after '80 should just bolt right on.
Would not hurt to pull out the inner slug/assembly to make sure it's clean and lightly coated with fresh grease. Very lightly, as packing it with grease like you would a bearing will just result in a recalcitrant action.
All the inner surfaces, including splines, cavities, spindle surfaces, and hub bits, should be lightly coated.

Also, when servicing the parts, except for cleaning and fine-tuning, removal only requires the six screws to remove the **** assembly and only the snap ring, or rings, to remove the inner slug as one assembly. You don't need to remove that little tiny screw that lets the inner splined sleeves and springs out. R&R'ing the hubs doesn't require the whole disassembly. Only if you want to dig into the inner workings is that necessary.

I wonder too, if there were any interim models? Or did they simply transition from the Spicer type, with all of it's parts and the large spring, directly to the Warn type with the two assembled halves?

Wow man, this book is frik'n awesome. Thanks.
Wish I would have known about it a long time ago. Written in 83.

 

Excellent! Glad you like it. And that one's in great shape it looks like too! Nice score.
