Lincoln Aviator: Front Drive Axle/Differential / Description and Operation - Front Drive Axle and Differential

The 6.5-inch ring gear rear differential axle has 3.31, 3.58 and 3.73 gear ratio versions.

Front Drive Axle and Differential

The front drive axle consists of:

A cast-aluminum center section, a removable cast-aluminum differential housing cover

Integral-type housing hypoid gear design (center of the pinion set below the centerline of the ring gear). Two opposed tapered roller bearings support the drive pinion in the axle housing

A drive pinion collapsible spacer, located on the pinion shaft, maintains pinion bearing preload. The pinion nut adjusts the preload

Differential bearing shims, located between the differential bearing cups and the axle housing, adjust the differential bearing preload and the ring gear backlash

A differential case, a 1-piece design with 2 openings to allow for assembly of the internal components and lubricant flow. Two opposed tapered roller bearings (differential bearings) support the differential case in the axle housing. Removable differential bearing caps retain the differential assembly in the axle housing

The bar code tag located on the RH side differential assembly contains the axle information

The front drive axle receives input from the transfer case by way of the front driveshaft. Rotational torque is transferred through the drive pinion to the ring gear, which in turn drives the differential case. Inside the differential case are the pinion gears which rotate on the stationary pinion shaft and the side gears which are splined to the axle shafts. The differential assembly is a gear arrangement that allows the drive wheels to be driven at different speeds and divides the input torque of the pinion gear between the axle halfshafts. The front axle transmits torque only and carries no vehicle load. CV-joints located at each end of the halfshafts allow the axle to remain stationary in relationship to front wheels, yet articulate at the knuckle. These CV-joints permit the wheels to be driven and turned at the same time.
