A flanged axle shaft assembly includes a shaft having a tubular wall and an open end, a flange hub having a central opening fitted over the shaft and secured to the open end, and an end wedge secured in the open end and urging the shaft wall into compressive engagement with the flange hub opening to provide for transmission of forces between the shaft and the flange hub. In a preferred method of assembly, the shaft is formed with a flared inner end stop against which the hub flange is mounted about the shaft. Forcing the end wedge into the shaft inner end expands the shaft wall into a characterized, such as splined, surface of the hub central opening to provide a high torque mechanical driving connection. The hub flange and a head of the end wedge are preferably also laser welded to the shaft.
