ABSTRACT:
A housing for differential mechanism is formed in two pieces using a cold flow-forming process. Each of the housing portions is formed with an internal hemispherical surface, and semi-circular recesses, which when aligned form circular recesses within which a pinion shaft is seated. A subassembly that includes the pinion shaft, pinion gears, side bevel gears, and a thin plastic liner surrounding the subassembly is located within a lower housing portion so that the pinion shaft is seated in the recesses. The upper housing portion is inserted within the upper portion and welded. A ring gear is joined to a housing portion.
