Abstract
A four-wheel drive recreational vehicle having an independent front suspension system and a clutch arrangement for normally driving the vehicle from the front wheels only, but capable of sensing slippage of the rear wheels to thereby couple the engine's output shaft to the front wheels as well. The front wheels are equipped with tires which are more narrow than those used on the rear wheels, but the tread width of the front wheels is made larger than that of the rear wheels to thereby provide adequate space for the driving connections between the front differential and the wheels so that only modest bending forces are experienced by the U-joint coupling the driven shaft between the front differential and the wheels' driven axles.
