A hub mechanism for four wheel drive vehicles. Movement of the clutch ring into and out of position for interengaging the pinion of the axle end and a housing portion of the wheel hub, is provided by a pair of opposed spring members. The first spring member provides continuous urging for disengagement. A second spring member is coupled to a camming mechanism that is activated by a manually operated dial. Turning the dial physically moves the second spring member relative to the clutch ring. In a retracted position the strong spring member is backed away from the clutch ring to permit disengagement. Opposite dial turning moves the strong spring member for urging engagement of the clutch ring with the pinion.
