ABSTRACT:
The present invention includes a differential housing and a method for forming the differential housing. The method includes the step of cold-working a first housing preform by one of a group consisting of spin-forming or flow-forming the inner surface of the preform into conformance with a contour of a first mandrel to form the differential housing. The method also includes the step of installing a differential mechanism subassembly including a plurality of gears and a pin in the differential housing. The method also includes the step of releasibly connecting a housing portion of the differential housing with one of a lid and a second gear assembly.
