Question: what is the difference between 4 wheel low and 4 wheel high?
Answer: What About This 4WD Low Range? ... Without an Auto setting, 4WD High is what you'd use in any situation that's low-traction but relatively high-speed—a dirt road or snowy paved road. 4WD Low is strictly for slow off-roading or places where torque multiplication would really help you out (like deep sand).
