REAR AXLE IDENTIFICATION FOR ORDERING REPLACEMENTS

Subject: REAR AXLE IDENTIFICATION

Model and Year: 1992 S TRUCKS

1992 S vehicles may be equipped with a 7.5" 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 vehicle 7.5" axle. All other assembly parts are common and interchangeable.

To identify where the axle assembly was built:

1. Locate the axle code on the axle housing (Figure 1).

2. Find the fourth letter (from the left ) of the code. K = St. Catherine, Canada C = Buffalo, New York

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
