A vehicle's transfer case divides engine power between the front, rear, or all four wheels. The case consists of a shaft that derives power from the transmission. The input shaft connects with two output shafts that direct the power to the front, rear, or both ends of the vehicle.
Part-time 4WD is a common type of transfer case. The technology enables drivers to select two-wheel, four-wheel high, or four-wheel low drive. Full-time 4WD sends power to the front and rear wheels all of the time. Some versions enable owners to lock the differential.
In the last decade, vehicles have become available with active 4WD transfer cases. The systems use electronic or mechanical components to regulate and adjust the power level that the front axle receives in order to prevent slipping. The system offers part-time transfer case benefits. But the transition occurs automatically. See our Junction City, KS Jim Clark Chevrolet-Cadillac technicians for all of your transmission needs.
