Abstract
An integrated pinion, bearing and coupling (PBC) assembly for use with a hypoid gearset in power transfer assemblies of motor vehicles. The PBC assembly includes a pinion unit having a pinion gear segment and a pinion stub shaft segment, and a coupler unit having a coupling flange segment and a coupler shaft segment. The pinion stub shaft segment surrounds and is in press fit engagement with the coupler shaft segment. A portion of the coupler shaft segment is deformed to be retained within one of a receiver groove and raised projections formed in the pinion stub shaft segment so as to fixedly secure the coupler unit to the pinion unit.
