    it is 4.56 gears
    not sure about the detroit, it could be because it has a open carrier. :thumb:

    in the one pic you can see the big hole in the carrier assbly the gear bolt to . if there are 3 total its a cov-lock ,if 4 total it open or locker, and if 4 look in the side holes for spider gears if there is any its open. if locker you should be ably to turn the pinon and both tires turn the same way. as above 4.56 and the other # are date code for gears.

    The number he gives also shows 3.73 gears (41 11), not 4.56 (41 9). You can't tell by looking if it has a detroit (it would be inside the carrier). The best way to check that is to spin one tire and see if the other spins the same way or opposite. If the other tire is spinning the opposite direction the carrier is open or has a gov lok. If both want to spin the same direction it has a detroit.

    yea you can, just look and see if you can see the spider gears, if you cant and there are 4 holes on the outside of the carrier then you have a detroit.

    11/85 = date of manufacture (month and year)

    Ummm...there's not a much easier way to figure it out. Get the brake drums and pinion just high enough off the ground to be able to turn...and give it a whirl. If it was out of a CUCV military truck then it almost def. has a detroit.
