Flow-formed differential case assembly

摘要

A differential case assembly includes a differential case and a pinless gear assembly. The differential case has an open end and a side wall with an interior surface. The pinless gear assembly includes a retainer insert and a side gear with a shaft extending outwardly therefrom. The retainer insert is disposed adjacent the interior surface of the side wall, The retainer insert defines at least a portion of an aperture that receives an end of the shaft to align the gear assembly within the differential case.
