GENUINE SPICER SERVICE PARTS
Should an axle assembly require replacement component parts, it is recommended that
Spicer Heavy Axle Service Parts be used. Spicer Heavy Axle Service Parts are manufactured
under the same rigid specification as are original equipment axle components. This assures
the customer who uses genuine Spicer service parts maximum reliability for a Spicer Heavy
Axle assembly. They may be obtained through your vehicle manufacturer. The use of nonoriginal Spicer service parts may cause premature compontent failure and may void the
warranty.
The items included in this book are currently being offered as service parts at the time of
printing. The part numbers and illustrations are provided specifically for reference purposes
only. Therefore, Spicer reserves the right to update this manual without notice or liability.
All axle assemblies are identified with two tags; one
located on the differential carrier, and the other located
on the right hand side of the axle housing.
AXLE IDENTIFICATION
The differential carrier tag contains the following:
Dana part number, julian date code, and ratio. Optional
items include customer part number, line set number, and
the last six digits of the vehicle serial number.
