Axle is 4:10. The one hub with no hub cover has a lot of rust inside, but that wheel actually spins freely. the other wheel with a Superwinch hub is near impossible to move by hand. I know it was freed up as the truck rolled and moved under it's own power. It could be a hub issue or maybe just the brakes are hanging up. I think the truck had not been run and moved in many years.
We took the diff cover off to see the ratio, and all the gears look good.
I'd be happy to open it up again for your inspection if you want.
