Abstract
A method for joining components of a vehicle drive axle assembly. The method includes heating an axle housing to a first predetermined temperature and cooling a pinion cartridge to be installed with the housing to a second predetermined temperature. Removing the axle housing from exposure to the first predetermined temperature and removing the pinion cartridge from the second predetermined temperature and rapidly installing the pinion cartridge within the axle assembly before the axle assembly and the pinion return to ambient temperature provides a frictional fit, joining the two components without use of additional fastening devices.
