Both right and left side #3 mounts must be replaced.

To repair this condition, use the following service procedure:

1. Raise vehicle. 2. Install jackstands to support frame. 3. Remove three nuts from the #3 mount insulator (refer to Figure). 4. Remove bolt and insulator. 5. Remove spacer. 6. Install a new #3 mount using the following parts:

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.
