KENWORTH IS RECALLING 3,423 MY 2004-2009 T2000, T800,T600, W900 AND T660 VEHICLES. INCREASED BRAKE EXCITATION IN A CERTAIN VEHICLE CONFIGURATION WHICH INCLUDES BENDIX DRUM BRAKES, WIDE BASE LOW PROFILE SINGLE TIRES, AND AN AG400 OR AG460 REAR SUSPENSION, DUE TO ITS UNIQUE BRAKE CLOCKING AND CAM TUBE LENGTH, CAN CAUSE FATIGUE AND CRACKING TO BRAKE ASSEMBLY COMPONENTS.
PACCAR IS RECALLING 130 MY 2004-2009 T2000, T800, T600, W900 AND T660 KENWORTH TRUCKS BUILT WITH AN AG400 REAR SUSPENSION, LONG STROKE BRAKE CHAMBERS, AND WIDE BASE TIRES (SUPER SINGLES). THESE VEHICLES MAY DEVELOP AN INCREASE IN LATERAL AND VERTICAL AXLE MOVEMENT. THIS MOVEMENT MAY CAUSE PART OR PARTS OF THE BRAKE ASSEMBLY (BRAKE CAM TUBE SUPPORT, BRAKE CHAMBER BRACKET, BRAKE CHAMBER, BRAKE SPIDER) TO DEVELOP FATIGUE CRACKS, POSSIBLY RESULTING IN THE FAILURE OF THE PART OR PARTS WITHIN THE BRAKE ASSEMBLY.
PACCAR IS RECALLING 4,883 MY 2006-2009 KENWORTH T600, T660, T800, W900, T2000 AND MY 2008-2009 PETERBILT 365, 367, 379, 384, 386, 387, 388 AND 389 TRUCKS. INADEQUATE STIFFNESS OF THE DIESEL PARTICULATE FILTER (DPF) BRACKET COULD RESULT IN SEPARATION OF THE DPF FROM THE CHASSIS.
ON CERTAIN TRUCKS EQUIPPED WITH CATERPILLAR C11, C13 OR C15 ENGINES, THE OIL FILL CAP CAN BECOME DISLODGED DUE TO CAP DAMAGE OR IMPROPER INSTALLATION AND BECOME LODGED IN THE U-JOINT OF THE STEERING DRIVELINE AND STEERING GEAR.
ON CERTAIN TRUCKS, THE REMOVABLE TOW HITCH ,WHEN USED TO TOW OR LIFT A VEHICLE, CAN FAIL DUE TO DEFECTIVE MATERIAL IN THE TOW HITCH.
ON CERTAIN TRUCKS, AN RA529 KING PIN RELEASE AIR VALVE WAS MANUFACTURED WITH THE INTERNAL SPOOL INSTALLED BACKWARDS. THIS RESULTS IN THE AIR OPTION OF THE KING PIN RELEASE SYSTEM BEING INOPERABLE. TO CORRECT THIS SITUATION, THE VEHICLE'S AIR LINES WERE REVERSED RATHER THAN REPLACING THE VALVE.
ON CERTAIN TRACTORS EQUIPPED WITH CATERPILLAR DIESEL ENGINES, THE VARIABLE VALVE ACTUATION OIL LINE MAY WEAR AGAINST THE SHARP EDGE OF THE CYLINDER HEAD IF NOT POSITIONED CORRECTLY.
ON CERTAIN TRUCKS EQUIPPED WITH THE BENDIX ELECTRONIC STABILITY CONTROL (ESP) SYSTEM, THE SYSTEM USES MULTIPLE SENSORS AND AN ELECTRONIC CONTROL UNIT (ECU) TO CONTROL VEHICLE UNDER STEER, OVER-STEER, AND ROLLOVER SITUATIONS. THE SYSTEM RELIES ON VEHICLE SENSORS TO BE FUNCTIONING AND ALIGNED PROPERLY. THE STEERING ANGLE SENSOR HAS THE POTENTIAL TO BE MISALIGNED WITH THE STEERING COLUMN SHAFT, THEREBY PROVIDING INCORRECT INFORMATION TO THE BENDIX ECU.
