Abstract: A differential housing includes a body including an outer surface. The body has a first end, a second end, and an intermediate portion extending therebetween. A ring gear support member extends outwardly of the body at the second end. A ring gear support surface forms a first section of the intermediate portion. The ring gear support surface defines a first outer diameter of the intermediate portion. A ring gear is mounted to the outer surface of the body. The ring gear includes an inner annular surface having a first region defining a first inner diameter and a second region defining a second inner diameter. The first region includes a sawtooth profile to establish a desired alignment of the ring gear and the body and the second region facilitating an interference fit with the ring gear support surface.
