DESCRIPTION AND OPERATION

DRIVELINE SYSTEM

The source of the drivetrain's power is generated by the engine and delivered to the transmission. The driveline
transfers the engine torque through the driveshaft to the axle.

z

On 2-wheel drive vehicles, power is transmitted through the transmission to the driveshaft and then to the
rear axle.

z

On 4-wheel drive vehicles, power is transmitted through the transmission and the transfer case. The
transfer case directs the power to the rear driveshaft and then to the rear axle. When engaged, it also
transmits power through the front driveshaft to the front axle.

The rear driveshaft is connected to the output shaft of the transmission and to the rear axle. The front driveshaft
is connected to the transfer case and to the front axle. Universal joints are used at both ends of the driveshaft to
allow for angular motions. Slip yokes are used to allow for any changes to the length of the driveshaft. The
engine torque enters the axle through the drive pinion, which rotates the ring gear. The ring gear is mounted to
the differential case, which contains the gears that transmit power to the rear axle shafts or front halfshafts.
These shafts rotate the drive wheels.

Vehicles have the following types of driveshafts:

z

One-piece rear driveshaft with two U-joints and a front slip yoke.

z

Two-piece rear driveshaft with three U-joints, a front coupling shaft, a center bearing and a rear
driveshaft.

z

One-piece front driveshaft with one front U-joint, a slip yoke and a rear CV joint.

For additional information on the front axle assembly, refer to FRONT DRIVE AXLE/DIFFERENTIAL-
FORD 8.8-INCH .

For additional information on the halfshaft, refer to AXLE SHAFTS (4WD) - F150 .

For additional information on the driveshaft, refer to DRIVESHAFT & UNIVERSAL JOINTS - F150
PICKUP .

For additional information on the rear axle, refer to REAR DRIVE AXLE/DIFFERENTIAL-FORD 8.8-
INCH or REAR DRIVE AXLE/DIFFERENTIAL-FORD 9.75-INCH .

The engine angle is built into the engine mounts. If the engine angle is out of specification, the engine mounts
must be inspected for damage.
