Subject: REAR AXLE RING AND PINION ASSEMBLY REPLACEMENT

Model and Year: 1992 C1 & C2, K1 & K2, G1, G2, G3 TRUCKS

Rear axle ring and pinion sets for 1992 C/K Utilities, Suburbans and 1992 G Vans are system balanced as an assembly. The assembly is balanced as a unit with the pinion flange weighted as a harmonic member.

When axle repairs dictate that a new ring and pinion gear set be installed, a new pinion flange must also be used. Discard the original pinion flange and refer to the appropriate GMSPO Parts Catalog for the proper service flange.

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.
