Differential Assembly: Application and ID

Driveline System
The driveline system consists of the:
^ driveshaft tube, slip yoke, U-joints and flange.
^ rear axle assembly with flange, pinion, ring gear, differential and axle shafts.

The source of the drivetrain's power is generated by the engine and delivered to the transmission. The driveline transfers the engine torque from the transmission through the driveshaft to the axle. The axle differential splits the torque between the axle shafts and sets the vehicle in motion.

Vehicle Certification (VC) Label Example:

The vehicle certification (VC) label is located in the driver door jamb. The axle code is on the VC label.

For information on the VC label, refer to Vehicle/Application and ID.

Axle Identification Tag Denoting Interchangeability Affected Internally (Part 2):

CAUTION: The axle identification tag is the official service identifier. Do not damage the tag. Always reinstall the tag after removing it for axle inspection/repair or axle identification will not be possible in the future.

The rear axle identification tag is located on the rear axle, attached by a differential housing cover bolt.

The axle identification tag identifies a particular axle design, a specific ratio, and if it is a conventional or limited slip (Traction-Lok(R) type. In addition, the plant code will not change as long as that particular axle assembly never undergoes an external design change. If, however, an internal design change takes place during the production life of the axle and that internal change affects parts interchangeability, a dash and numerical suffix is added to the plant code. This means that as an assembly, both axles are interchangeable; however, internally they are different. Therefore, each requires different internal parts at the time of repair.
