I've got a pair of older Allstate locking hubs to refurbish and use.
Upon initial inspection they're clean as can be-maybe too clean.
The pawls and springs are all in good condition and everything
operates smoothly. I was taken aback when i found only a light
oil type lube inside-no grease. Whats the proper lube here? I can
see that a heavy grease would foul the spring and pawl action.

When they are unlocked the free wheeling wheel simply rotates the entire outer hub housing around the center splined section. So this area will need a light grease. Most hubs manufacturers recommend regular chassis lube which would be #2.

The areas of the hub that have movement between each other when operating the locking mechanism need lube as well and the splines also should be lubed.

I had old timers tell me they would clean all the parts, assemble the hub dry then pour 90 weight gear oil into the hub, let it sit a bit, then dump out the extra and install them. I never did it but their way was a lot "cleaner", I used a lot of rags my way. I cleaned the parts then greased them as I assembled them. I would coat with grease THIN on the mechanism pieces that moves in side the hub, and then pack plenty in the center were it will "SPIN" against when it is not engaged. Just remember to much grease and they can get sticky or will not engage.......to little they can wear out and overheat and lock up. Its a fine line but I lean on cautions side....If they stick/don't engage I can pull them down and clean some grease out, to little and I have to open my wallet and replace parts.

I've always used ATF on mine. Same idea as Hullroad's oil description. Soak, drain, bolt on twice a year, unless more is necessay. Of course I lived in Edmonton, Alberta when this was suggested to me. I still do it. They never freeze and turn with two fingers... Care and attention though...

Disassembled hubs, sandblasted the outer shells, primed, painted
then reassembled. Went with soap base lithium complex NLGI
No2 GC-LB (cuz i had it on the shelf). Painted it on lightly with a 3/8 wide stiff bristle brush-could lightly coat all parts before reassy. About ready
to put 'em back on the truck this weekend. Thanks to all for info.
Gotta love something to do in the winter!!

Real nice job Rick. And I think very worth the effort cause a lot of folks will be looking at your hubs, scratching their heads and asking where you ever found a pair of those! Wink

Shame you didn't post a few more teardown, clean/insp, reassemble photos in your album!!! Crying or Very sad

In retrospect i wish i had taken more fotos, but the hubs are of
such simple design it just didnt occur to me that better documentation
might benefit someone else down the line.. Embarassed

Hubs back on truck. They're hunky-clunky lookin but have a takin care
of bizness attitude. Took a trip to the gravel pit yesterday and they
performed without a hitch. Two finger operation to engage-disengage.
