Re: Advantage to six wheel drive?
With a dead axle, the axle does not rotate. The wheel has bearings in it that ride on the shaft and the drive sprocket is attached to the wheel.
With a live axle, the axle and wheel are connected together. The axle rotates on bearings and the drive sprocket is attached to the axle.
With the WCD setup, the wheel is cantilevered. It is very easy to maintain since you don't have to remove the drive sprocket and chain to remove the wheel.
