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.
