- The transfer case receives power from the transmission and sends it to both the front and rear axles by gears, hydraulics, or chain drive. Four-wheel-drive trucks intended for off-road use this feature controlled by the driver. The driver can put the transfer case into either “two-wheel-drive” or “four-wheel-drive” mode. This is sometimes accomplished by means of a shifter similar to that in a standard tranmission. Some vehicles are electronically operated by a switch instead.
- Transfer cases that are designed to allow for normal road use synchronize the difference between the rotation of the front and rear wheels, in much the same way the differential acts on a given axle. This is necessary because the front and rear tires never turn at the same speed. Different rates of tire rotation are generally due to different tire diameters (since front and rear tires wear at different rates) Different gear ratios occur in the front and rear differentials since manufacturers will often have a slightly lower ratio in the front vs. the rear. This helps with control. If the transfer case did not make up the difference between the two different rates of rotation, binding would occur. The transfer case becomes damaged.
- Lastly, transfer cases designed for off-road use mechanically lock the front and rear axles. For example, one axle slips on a slippery surface and the other has better traction.
