Abstract
A dual wheelend for an axle assembly having a rotatable axle shaft. The wheelend comprises a spindle defining a first axis. An intermediate hub is supported on the spindle for rotation about the first axis during rotation of the axle shaft. An inner wheel hub and an outer wheel hub are adjacent one another and are each supported on the intermediate hub for rotation about the first axis. A differential mechanism interconnects the inner and outer wheel hubs. A pin is disposed through a pinion along a second axis and couples the differential mechanism to the intermediate hub for driving the wheel hubs during rotation of the intermediate hub and permitting relative rotation between the wheel hubs relative to the intermediate hub. The pin includes proximal end with a head disposed on the proximal end for engaging the pinion and sandwiching the pinion between the head and the intermediate hub.
