Transmission and Drivetrain: Application and ID

Vehicle Certification (VC) Label Example:

Axle Identification Tag Denoting Interchangeability Affected Internally:

CAUTION: The axle identification tag is the official identifier. Do not damage the tag. Always reinstall the tag after removing it for axle inspection/repair.

The plant code denotes a particular axle design and specific ratio. 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.
