Default Help identifying these '40-style rear hubs

Hi Folks:

I'm trying to figure out what I have here. I purchased some '40 style rear hubs. The ones with the larger diameter open was bare. The other one had the bearing and grease seal still in there, so I didn't realize the difference under I removed those parts.

What do I have? It appears the one with smaller diameter has those parts pressed in, but I'm not sure.

Any help would be appreciated.

Thanks,

Tim

Ford used two sized bearings. Thay all fit the axle stubs but must be used with the corresponding hubs. 32-36 was bigger at 3.19. 36-48 at 2.84

Thank you.

So if the correct bearings are used, they can be mixed and matched since the axle taper is the same?

Yes. I have taken 32 hubs off and installed 40 hubs with no problems. Just use the bearing that goes with the hub.

Question Andy: Are the drum mounting face offsets the same? Given the different brake shoe widths - are the 40's different than the 32s (for instance)?

But, aren't the hub and drum all one piece up through 37 or maybe even 39 (except for those wide-five ones that were made with a big hub and narrow drum, which we are sure isn't the kind pictured)? So these would have to be made for a 40 or later?
