Abstract
The present invention discloses a differential housing and a method operable to form the differential housing. The method includes the step of disposing a member having an outer surface on a mandrel. The member in the exemplary embodiment of the invention is a ring that enhances the strength of the finished differential housing. The method also includes the step of cold-working a housing preform by flow-forming the inner surface of the housing preform into conformance with the mandrel and with the outer surface of the member after said disposing step. The member is disposed in situ as the housing preform is cold-worked to produce the finished differential housing.
