Full-Time Four Wheel Drive (F4WD) Front Differential Assembly

The Full-Time Four Wheel Drive (F4WD) Front Differential Assembly consist of the following components.

The front differential assembly on Full-Time Four Wheel Drive (F4WD) model vehicles does not have a central disconnect feature in order to engage and disengage the front differential assembly. The left and right axle shafts are connected directly to the differential case assembly. This allows the axle shafts and the driveshaft to spin continuously. The transfer case controls the amount of torque applied to the front differential assembly. The remaining components are the same as the Selectable Four Wheel Drive axle.
