MODELS: 1992 S-TRUCKS (2WD JIMMY/SONOMA)


1992 S-trucks may be equipped with a 7.5-inch axle manufactured in either St. Catherine, Canada or Buffalo, New York. Both axle assemblies have the same final assembly part number, but use a different housing assembly service kit and wheel bearing seal depending on where the axle assembly was manufactured. The correct housing assembly service kit and wheel bearing seal must be used when servicing a 1992 S-truck 7.5-inch axle. All other assembly parts are common and interchangeable.

To identify where the axle assembly was built:
