housing with an inner surface and an outer surface for a vehicle driveline component a retention element disposed in the housing and at least one deformation formed on the inner surface operatively in contact with the retention element to retain the vehicle driveline component in the housing this design and method of manufacture eliminates the need for differently sized spacers because the location of the deformations and the retention element can be tailored relative to the actual location of the components to ensure proper distance between components and the retention element moreover because the spacer may be used as the retention element the need for a snap ring is eliminated application_number US 22639002 A description fig1 shows portions of an example assembly 20 for use in a vehicle driveline the assembly 20 includes a housing 22 which is a clutch housing in the illustrated example the housing 22 has inner surface 24 and an outer surface 26 the housing 22 includes a series of splines 28 and grooves 30 around the circumference of the housing a plurality of clutch plates 36 are supported within the housing between a spacer element 38 and a support portion 40 at one end of the housing the clutch plates 36 are conventional in previous designs of clutch housings a snap ring groove was provided and a.
