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. A propeller shaft connects the transfer case to the
front axle. The differential carrier assembly uses a conventional ring and pinion gear set to transmit the driving
force of the engine to the wheels. The open differential allows the wheels to turn at different rates of speed
while the axle continues to transmit the driving force. This prevents tire scuffing when going around corners
and premature wear on internal axle parts. The ring and pinion set and the differential are contained within the
carrier. The axle identification number is located on top of the differential carrier assembly or on a label on the
bottom of the right half of differential carrier assembly. The drive axles are completely flexible assemblies
consisting of inner and outer constant velocity CV joints protected by thermoplastic boots and connected by a
wheel drive shaft.
