If you owned a four-wheel drive vehicle and did not have a transfer case, you would need to call it a two-wheel drive. Most 4x4s are defined by their transfer cases. Also known as gearboxes, off-road enthusiasts rely on transfer cases for their strength, durability and their ability to evenly distribute power. Here are a few more facts about transfer cases.

Here is the bottom line on transfer cases: They take power from the engine and divide it to the front and rear axle. From there, the power is sent to all four wheels. Inside the transfer case is an input shaft that is spun by the transmission. Connected to the input shaft is a pair of output shafts. The output shafts spin the front and rear driveshaft, which is part of your vehicle's drivetrain.
