1997 CHEVROLET SILVERADO 2500 Steering Problems

I HAVE A1997 CHEVROLET 6.5T DIESEL, I WAS DRIVING HOME FROM WORK DOING ABOUT 45 MPH CROSSING A STOP LIGHT AND THE TRUCK JUST SHUT OFF FOR NO REASON AND A SEMI WAS BEHIND ME AND ALMOST PLOWED IN TO THE BACK OF MY TRUCK BUT HE WAS ABLE TO GO AROUND AT THE LAST SECOND. I WAS ON THE FREEWAY DOING 70 MPH AND THE TRUCK DID THE SAME THING JUST SHUT OFF FOR NO REASON AND A CAR ALMOST HIT ME BUT WAS ABLE TO STOP IN TIME. ON ALL OCCASIONS I LOST ALL POWER TO EVERYTHING BRAKES,STEERING AND ENGINE POWER. THIS HAS HAPPENED SEVERAL TIMES BEFORE AND AFTER THE TWO ABOVE. FOUND OUT THAT GM HAD PUT OUT AN UNDER THE TABLE RECALL OF THE PMD AND INJECTOR PUMP ON THE 6.5T DIESEL MOTOR 12YR/100,000MILES BUT DID NOT PUBLICLY SAY ANYTHING. THE OTHER THING THAT I JUST...

DT*: THE CONTACT STATED THE VEHICLE WAS HARD TO STEER AT VARIOUS SPEEDS AND SUDDENLY PULLED TO THE RIGHT CAUSING THE DRIVER TO LOSE CONTROL. THE INCIDENT OCCURRED AFTER AN INDEPENDENT REPAIR SHOP REPLACED THE IDLING ARM AND PITMAN ARM. THE FRONT END WAS REALIGNED BUT THE PROBLEM PERSISTED. TWO DIFFERENT INDEPENDENT REPAIR SHOPS DETERMINED THERE WAS A DEFECT. THE DEALERSHIP WAS NOT CONTACTED. UPDATED 9/5/2006 - THE FAULTY PART WAS THE STEERING WHEEL SPEED SENSOR. *NM

WHILE IN MOTION AND IN A SLOW TURN THE AMOUNT OF FORCE REQUIRED TO TURN THE STEERING WHEEL CHANGES, RESULTING IN SUDDEN AND ABRUPT MOVEMENTS. THIS SOMETIMES RESULTS IN LOSS OF CONTROL OF THE VEHICLE. *JG *JB
