The 4 wheel drive is vacuum controlled through the transmission. It has a shift actuator on the front axle sometimes the sifter can stick if it is not used somewhat frequently. Or is it that the light just doesn't come on? Cause the truck should hop when the 4 Wheel drive is engaged and you turn sharply
