The drive train consists of a group of vehicle parts that deliver and generate power to your 4WD vehicle. Contrary to popular belief, the engine and motor don't belong to the drive train. The drive train's primary function is to route the engine to the driving wheels to rotate the axle. The drive train includes a drive shaft and differentials to transmit motive power to all four wheels.
As your vehicle's speed changes while driving, the drive train helps maintain the engine's constant speed by changing the gearbox ratio through automatic or manual transmissions. A 4WD vehicle usually also has a transfer case whose function is to transfer motive power to the front wheels when four-wheel drive is activated and usually has a low range selector to reduce the gearing range for better control and higher torque at lower speeds offroad.
