The Dana 27 rear axle was the standard WWII jeep axle. (41-45) It is also seen on the very early column shift CJ2A Jeeps in late 45′ and early 46′. This axle has solid shafts with a flange cast on the ends. These look just like a miniature 3/4 ton truck rear hub where the axle hub sticks out. (see Picture) The housing is rather boxy looking and the cover plate is almost square but with rounded corners. The early cover plates were heavy cast metal and the late ones were stamped sheet metal.
