A FEW MONTHS AGO I NOTICED A NOISE FROM THE ENGINE COMPARTMENT AT LOW IDLE,I CHECKED IT OUT AND FOUND THE SUPPORT BRACKET FOR THE POWER STEERING PUMP WAS LOOSE.THE 2 BOLTS THAT SECURE IT TO THE ENGINE HAD BOTH SHEARED OFF,THIS CAUSED CONSIDERABLE VIBRATION TO OCCURE FROM THE POWER STEERING PUMP.
HEAD GASKET FAILURE ON SEVERAL OCCASSIONS.

GENERAL MOTORS HAS DETERMINED THAT SOME 1987 GMC S/T MODEL TRUCKS MAYEXPERIENCE FRACTURE OF THE POWER STEERING PUMP SUPPORT BRACE. THISCONDITION CAN IN TURN LEAD TO POSSIBLE FRACTURE OF THE POWER STEERINGPUMP MOUNTING BRACKET AND/OR LOSS OF THE SERPENTINE ACCESSORY DRIVEBELT. LOSS OF THE DRIVE BELT WOULD RESULT IN LOSS OF A/C, GENERATOR,POWER STEERING ASSIST AND WATER PUMP OPERATION.ANALYSIS: THERE ARE NO REPORTS IN THE ODI LETTER FILE REGARDING THISPROBLEM.ALTHOUGH G.M. HAS 153 COMPLAINTS, MOST OFWHICH ARE WARRANTY CLAIMS, ONLY TWO ACCIDENTS HAVE BEEN REPORTED THATWERE ALLEGDLY CAUSED BY THE FAILURE OF THE P/S SYSTEM. P/S ASSIST FAILURESHOULD NOT NEGATE STEERING CONTROL EVEN THOUGH THERE IS AN APPRECIABLEINCREASE IN STEERING EFFORT.======
