Abstract

An inboard hub lock assembly integrated into a steering knuckle. Teeth are provided on an end of the CV housing and an adjacent flange extending from the wheel hub. A clutch member with corresponding teeth is movable between 1) an outboard position engaging the CV housing teeth and the wheel hub flange teeth, thereby transmitting drive power from a stub shaft to the wheel hub, and 2) an inboard position engaging only the CV housing teeth, thereby permitting the wheel hub to rotate freely relative to the stub shaft. A spring biases the clutch member to a 4×2 mode fail safe position by biasing the clutch member to the inboard non-engaging position.
