Please discard PI02003C. The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI. Condition/Concern While performing a front end alignment it may be noticed that the upper control arm bracket alignment pin is missing. This pin serves as a pilot for the alignment cam when adjusting the front caster and camber. Recommendation/Instructions If the pin is missing, a 1/4 inch dowel rod or a punch can be utilized as a temporary alignment aid to properly center the cam to the bracket, while making adjustments and torqueing the control arm nuts Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these 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 your GM dealer for information on whether your vehicle may benefit from the information. WE SUPPORT VOLUNTARY TECHNICIAN CERTIFICATION 1
