POWER RACK & PINION DAMAGE DURING DISASSEMBLY

To prevent damage when removing the valve and pinion assembly from the housing on a rack and pinion steering gear, a press must by used (Figure 1). Hammering on the threaded end of the pinion to drive the valve and pinion assembly out can cause the valve pin to shear. This will result in an inoperative valve which cannot be repaired, but must be replaced.

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.
