Why does 4 wheel drive reduce wheel slip?
Four-wheel drive minimizes wheel slip because it increases the amount of longitudinal force the tires apply to the ground. Longitudinal force propels a vehicle forward during acceleration and slows it down during braking. The more longitudinal force applied to the ground, the less wheel slip.
What happens when a 4 wheel drive switch is bad?
A bad switch may cause the four-wheel drive system to be stuck in the permanently engaged, or disengaged mode. This is an issue as a permanently switched on four-wheel drive system will cause accelerated wear on the components, while a permanently switched off will leave the vehicle without four-wheel drive.
