Service (split ring) seal kit Part Number 26010340 is now available and can be installed on all vehicles equipped with power rack and pinion steer'lng gears with aluminum valve body housings. The service seal kit replaces the previous solid rings.
The special split rings are designed to expand into the seal wear grooves which may exist in the valve body housing and seat against the bottom of the grooves. This will ensure power steering assist when cold.
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.
