When installing a rear pinion bearing outer race on 1981 through 1984 7 1/2 inch axles, use installer J-29609 with drive handle J-8092. The 1984 chassis Service manual lists J-6197 as the required Rear Pinion Bearing Outer Race Installer, which is incorrect. Update your chassis service manual to show J-29609 as the correct tool number.
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.
