Full-Time Four Wheel Drive (F4WD) Front Axle Description and Operation
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 GMC Sierra, 2002 Chevrolet Tahoe, and 2002 Chevrolet Suburban. However, it is still accessible from the selected car via links, so may be relevant.
The Full-Time Four Wheel Drive (F4WD) Front Axle consist of the following components:
- Differential Carrier Housing
- Differential Assembly
- Output Shaft (Left Side)
- Inner Axle Shaft Housing
- Inner Axle Shaft (Right Side)
The front axle on Full-Time Four Wheel Drive model vehicles does not have a central disconnect feature in order to engage and disengage the front axle. The left and right axle shafts are connected directly to the differential case assembly. This allows the axle shafts and the propeller shaft to spin continuously. The transfer case controls the amount of torque applied to the front axle. The remaining components are the same as the selectable four wheel drive axle.
