If the wheels couldn't rotate at different speeds, your vehicle's tires would display a wheel hop effect, thereby making cornering a rough experience for both you and your tires.So, don't be indifferent toward your differential. It plays a vital role in moving your vehicle and ensuring a smooth ride.Radiator Contamination:When an engine or transmission fails and needs to be replaced, often, the vehicle's radiator must be replaced as well.
