I HAVE A 2002 CHEVY SILVERADO 1500 TRUCK, AND HAD A NEW SET OF TIRES (OEM SIZE), A NEW NAPA HUB BEARING ASSEMBLY AND A NEW NAPA INNER TIE ROD. THIS WORK WAS PROFESSIONALLY INSTALLED BY A CERTIFIED ASE MECHANIC AT A LOCAL REPAIR SHOP ON JULY 3, 2013. THE TIE ROD FAILED ON JULY 29, 2013. THE HUB BEARING AND THE INNER TIE ROD WERE REPLACED DUE TO NORMAL WEAR. THANKFULLY - THIS HAPPENED WHILE I WAS BACKING OUT OF MY DRIVEWAY AND NOT LAST WEEKEND DOING 70 MPH ON THE HIGHWAY WITH MY FAMILY IN MY TRUCK. FAILURE OF THIS PART ON THE HIGHWAY COULD HAVE COST ME MY LIFE, MY FAMILY'S LIVES AND THE LIVES OF EVERYONE ELSE IN MY UNINTENDED PATH. VEHICLE WAS "REPAIRED" BY THE LOCAL SHOP IN THE DRIVEWAY AND THEY SHOWED UP WITH A REPLACEMENT NAPA INNER TIE ROD. I SEE ON THE BOX THAT THIS PART IS MANUFACTURED IN CHINA. I DID NOT WANT THAT PART ON MY VEHICLE AND TOLD THEM THEY COULD INSTALL IT FOR A ONE-TIME TRIP TO THE SHOP BUT THEN I WANT IT CHANGED TO ANOTHER BRAND. THEY OBLIGED AND FOUND ANOTHER MANUFACTURER. THE NAPA PART IS ES3478 - INNER TIE ROD. *TR

STOPPING THE VEHICLE, THE ANTI-LOCK BRAKES WOULD KICK IN AT AROUND 3 TO 5 MILES PER HOUR AND THE VEHICLE WOULD NOT STOP, WOULD ROLL A FEW MORE FEET. ALMOST HIT A WOMAN AND CHILD IN CROSS WALK, HAD TO STAND UP ON BRAKES. THIS NOT STOPPING HAPPENED 5 OR 6 TIMES, THIS WAS THE CAME REACTION AS IN 2005 RECALL, CALLED GM. GM CHEVROLET CUSTOMER ASSISTANCE CENTER SAID, GO AND GET THIS PROBLEM CONFIRMED BY A GM DEALERSHIP, DID OCT. 9, '08 AND THEY SAID CORROSION BUILD IN SAME AREA, BUT BECAUSE RIGHT FRONT HUB WAS REPLACED WITH A NON GM PART (AFTER MARKET PART) THEY HAVE NO RESPONSIBILITY. THIS HUB CAME WITH THE SENSOR ATTACHED. IN 2005 MY 2002 CHEVROLET SILVERADO WAS ISSUED A RECALL FOR SEVERE CORROSION AREA BETWEEN THE FRONT HUB/BEARING ASSEMBLY AND THE WHEEL SPEED SENSOR. THEY FOUND THE LEFT SIDE SENSOR WAS MISSING AN O-RING, THEY INSTALLED UNDER THE RECALL. THE VEHICLE IS DOING THE SAME THING AND A LOCAL DEALERSHIP SERVICE DEPARTMENT CONFIRMED THIS SAME CORROSION PROBLEM. CALLED CHEVROLET CUSTOMER ASSISTANCE CENTER OCT 10, 08. GM CHEVROLET CUSTOMER ASSISTANCE CENTER CALLED ME MONDAY OCT, 20, '08 AND SAID THAT ONCE THE RECALL WAS FIXED, (HOW DID THEY FIX CORROSION) THE SAME PROBLEM IS NOW MY PROBLEM. WHEN I DROPPED OFF THE VEHICLE THE BRAKES WERE BAD, WHEN I PICKED IT UP AT THE END OF THE DAY THEY WERE 10 TIME WORSE, REALLY UNSAFE TO DRIVE. THEY DID NOT CHARGE ME A DIME, SAID THAT THEY WOULD WORK IT OUT WITH LOCAL REP. I WILL GET THE VEHICLE FIXED, BUT HOW DOES THIS CORRECT THE PROBLEM? *TR

ODI OPENED PE03-057 TO ASSESS PARKING BRAKE INEFFECTIVENESS IN THE SUBJECT VEHICLES.THESE VEHICLES ARE EQUIPPED WITH FOUR WHEEL DISC BRAKES THAT INCORPORATE A SINGLE-SHOE DRUM-IN-HAT PARKING BRAKE INDEPENDENT OF THE SERVICE BRAKES.COMPLAINT AND WARRANTY DATA INDICATE THAT THE PARKING BRAKE LININGS TEND TO WEAR OUT EARLY IN THE LIFE OF THE VEHICLE (AT AN AVERAGE OF 24 MONTHS IN SERVICE), REDUCING THE PARKING BRAKE SYSTEM'S TORQUE BELOW THAT NEEDED TO IMMOBILIZE THE VEHICLE.GM HAS ATTRIBUTED THIS ACCELERATED WEAR TO FOREIGN MATERIAL INTRUSION AND A FAILURE OF THE BRAKE SHOE TO PROPERLY SELF-CENTER WITHIN ITS BRAKE DRUM.EFFECTIVE WITH THE START OF MY 2003 PRODUCTION, A NEWER REDUCED FORCE HOLD-DOWN CLIP WAS INTRODUCED TO FACILITATE BRAKE SHOE DISENGAGEMENT FROM THE DRUM SURFACE.THIS PART IS ALSO AVAILABLE AT THE SERVICE LEVEL FOR THE MY 1999-2002 VEHICLES.GM HAS INDICATED THAT THE PAKING BRAKE IS INTENDED TO OPERATE IN CONJUNCTION WITH THE TRANSMISSION TO IMMOBILZE PARKED VEHICLES, AND THAT IN MANY CASES, ACCELERATED PARKING BRAKE LINING WEAR IS CAUSED BY ROUGH USE, VEHICLE MODIFICATIONS, AND DRIVING WITH THE PARKING ENGAGED. ODI HAS UPGRADED THE PRELIMINARY EVALUATION TO AN ENGINEERING ANALYSIS TO GATHER FURTHER INFORMATION CONCERNING PARKING BRAKE USAGE FACTORS AND THE CIRCUMSTANCES SURROUNDING THE SEVENTEEN REPORTED VEHICLE CRASHES.
