REAR SUSPENSION BOTTOMING HIGHER RATE SPRING USAGE

IN CASES WHERE THE REAR SUSPENSION BOTTOMS OUT ON CUTLASS CIERA MODELS WHEN CARRYING REAR SEAT PASSENGERS, HIGHER RATE REAR SPRINGS MAY BE INSTALLED. THESE HIGHER RATE SPRINGS ARE NOW IN PRODUCTION AND CAN BE OBTAINED FROM GMWDD. PART NUMBERS CAN BE OBTAINED BY REFERRING TO THE APPLICABLE SPRING USAGE CHART. IT WILL BE NECESSARY TO KNOW THE GAWRR (GROSS AXLE WEIGHT RANGE REAR) AND TIRE SIZE WHEN REFERRING TO THE SPRING USAGE CHART.

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.
