A shaft assembly that includes a propshaft member and a constant velocity joint. The constant velocity joint has an outer race, which is coupled for rotation with the propshaft member, an inner race, a plurality of bearing balls disposed between the outer and inner races to transmit rotary power therebetween, a shaft member coupled for rotation with the inner race, and a boot assembly that is sealingly engaged to the outer race and the shaft member. The shaft member defines a coupling portion that extends from the boot assembly. A method for coupling a shaft member to a driveline component is also provided.
