The drivetrain transfers power from the engine to all drive wheels evenly, also varies the amount of torque.
One of its component is the differential which is the mechanical component that spins both the left and right wheels, when a vehicle makes a turn it lets them rotate at different speeds.

The differential fluid provides lubrication to the internal components since heat, pressure and friction slowly breaks down the additives in the differential fluid.
Another important component are the transfer cases which are found on four-wheel drive and all-wheel drive vehicles. It is a gearbox that divides the transmission power output between the rear differential and the front differential.

Transfer case fluid provides lubrication to its respective internal components. Small particles of metal sometimes chip off the gears as they wear; these particles mixes with the fluid. Sometimes fluids also get contaminated with water.
