2. Squeak or chirp noise from rear leg latch plate and handle.

Cause:

------ 1. Rubber bumper located on left side of seat at folding hinge (See Figure 1) missing or deteriorated.

2. Insufficient or lack of lubrication on latch plate.

1. Install new bumper, P/N 12508731. (Figure 1)

2. Apply GM Lubriplate lubricant, P/N 1050109 or equivalent to both ends of latch plate on both sides of seats. (Figure 2)

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.
