The front hubs? They aren't lockouts.

That would explain why they looked different in the picture. Don't think I've ever seen one without some kind of locking hubs, makes your truck even cooler, great find.

As I understand it, that's actually the way they came from the factory. Lock outs were an option, added on by the owner.

Re: 66 k20

I have never seen 60 -66 trucks without lockout hubs....very interested to know if that is factory. I see on my build sheet that my Dana hubs were an option (F76) so I suppose it's possible to order without the lockouts. Either way nice truck.

Re: 66 k20

Yes, locking hubs were an option. The truck I got my front axle off did not come from the factory with lockouts. While it did not have a build sheet, I could tell because it has aftermarket hubs ( the Cutlas brand I referred to earlier, and have never seen another set of), but also there was no Spicer instruction sticker by the rearview mirror, just the transfer case shift pattern sticker. I'm thinking this is how your truck must be. Probably a lot of government and utility trucks (like mine) did not come with hubs, but they were added later when the trucks were sold to the public. As I understand it the only hubs offered by the factory were Spicer brand, so Warns and others were added later.
Anybody out there able to back this theory up or have other information?
Next time you post pictures ( and we all want to see more) can you take some of your non-locking hubs? Like I said I have never seen any except in the factory book
Thanks, Tom

Thanks for the pictures. Wow, those tires and split rims look even scarier than the ones that were on my truck when I pulled it from the barn.
BTW- Don't know if you have ever dealt with this era 3/4 ton 4x4, but front brake parts very hard to find.Took me a year to find everything needed. Happy to share sources, as would hate to see that cool original axle turned into a boat anchor for lack of some parts.
Good luck with the project, glad it found a good home.

Iíve got no intention of scrapping the front axle. Iíve done a little digging into brake parts as Iím sure the wheel cylinders are going to be junk. Ive found some stuff in the older NAPA catalogs that are available online but ill certainly keep you in mind for sources when I get to that point and I appreciate your help. I have found a place that has seals and bearings for both the 44f and the Rockwell Iíd be happy to share that if you could use it.

When I was taking those pics I noticed the date code on the tires was 1979.

Re: 66 k20

Warn locking hubs were offered in the Chevrolet Silver Book that was supplied to every dealer. The Silver Book came out each year with listed vendors of many attachments from light trucks to heavy duty.

If you look in my literature link , there's information and part numbers for the Rockwell T-221 as well as a 1963 Silver Book.

Biggest problem I had was finding front drums. Hopefully yours are OK, would suggest miking them now to see. Most sources don't list them anymore, and the ones that do will try to sell you 1/2 ton or 2WD, neither of which will work. Rears are still out there but also won't work in front. Fortunately there are some options, let me know if you need help.
I've had great luck with Torque King for the 44f and 221 stuff, is that who you use? If not please share.
Tom

Yes, Torque King is who I've got bookmarked also.

Very nice progress! Great to see it moving.

Sure you know, to make sure the T221 is at proper fluid level, very important.
