Always check the individual components for OEM identification numbers as you do replacements. Assembly or mixing of wrong parts could lead to premature failures. Always check compatibility of parts before final assembly Use replacement charts and reference notes to determine correct replacement parts. Check with the OEM for vehicle build data if identification of components cannot be done. Always use Spicer Genuine replacement parts, Failure to use Genuine Spicer replacement parts could lead to premature failures in assemblies and could void existing warranty on the component or axle assembly involved.
