Model Identification
Introduction
Locating Model Designation Information
• Axle Model Identification, Part Number and / or Serial Number are located on the axle centerline. This information will help to locate
information in this book and to identify the correct parts for servicing.
• Axle Housings are identified by the specification number stamped on the rear right-hand side of the axle housing. This number identifies all
components of the axle as built by Spicer, including OEM special requirements such as yoke or flange. Some axles may also include an
identification tag as shown.
• The axles illustrated in this book are found on a number of different axle shafts, according to OEM specifications.
When ordering replacement axle shafts, note the part number stamped into the flange.
