I pulled the cover to make sure these axles were 3.73s like they are supposed to be. Upon pulling the 10 bolt front diff cover, I see a gov lock sitting in there, and an aftermarket stamped ring gear that says 41x10. I go to the rear 12 bolt and turn the yoke, and both drums turn the same direction. I pull the cover and there are regular spider gears in it. So why are both sides turning foreward? And on the rear ring gear it is stamped 37:9. That divides out to a 4.0. Whats up with that? A 4.0 ratio 12 bolt non posi that acts like one and a gov-locked front 4.10 from the same truck.
