Abstract: An axle drive bevel gear differential arrangement for a motor vehicle is disclosed having a two part differential case including a main part and an end closure part. A ring gear is coaxially mounted on the part and has a hidden end face which faces the differential case parts and has an outside crown point diameter only slightly larger than the outside diameter of the differential case. A plurality of threaded machine bolts extend through aligned bores in said case parts for threaded reception in blind bores in said ring gear hidden end face so as to secure the two case parts and the ring gear together in a compact minimal diameter arrangement.
