Defect

PACCAR IS RECALLING CERTAIN MODEL YEAR 2007-2008 KENWORTH AND PETERBILT VEHICLES MANUFACTURED FROM FEBRUARY 2, 2006 THROUGH APRIL 30, 2007. THE BEARING SURFACES OF THE EXTENDED LUBE UNIVERSAL JOINT THAT ATTACHES THE INTER-AXLE DRIVELINE TO THE DRIVE AXLE MAY BECOME PREMATURELY WORN DUE TO BREAKDOWN OF LUBRICATION AND/OR EXCESSIVE HEAT. PREMATURELY WORN BEARING SURFACES MAY RESULT IN THE U-JOINT BECOMING LOOSE AND/OR BINDING. THIS CONDITION MAY RESULT IN UNIVERSAL JOINT FAILURE, ALLOWING THE INTER-AXLE DRIVELINE TO DETACH FROM THE AXLE.

Consequence

DETACHMENT OF THE DRIVELINE FROM THE AXLE MAY CAUSE THE VEHICLE TO LOSE POWER AND BECOME DISABLED IN THE ROADWAY. ALSO, THE DRIVELINE COULD DROP FROM THE VEHICLE INTO THE ROADWAY INCREASING THE RISK OF A CRASH.

Remedy

PACCAR IS WORKING WITH ITS SUPPLIER TO REMEDY THE VEHICLES FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN DURING FEBRUARY 2011. OWNERS MAY CONTACT KENWORTH AT 425-828-5440 AND PETERBILT AT 940-591-4196.

Defect

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.

Consequence

CRACKING CAN CAUSE A COMPLETE FRACTURE OF THE CAM TUBE, WHICH COULD INCREASE STOPPING DISTANCE AND DECREASE PARKING BRAKE HOLD CAPABILITY.

Remedy

DEALERS WILL INSPECT THE REAR AXLE BRAKES ASSEMBLY, REPLACE CRACKED REAR AXLE BRAKES ASSEMBLY COMPONENTS WHERE REQUIRED, AND INSTALL CAM TUBE SUPPORT BRACKETS ON ALL REAR AXLE WHEEL ENDS FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN OR BEFORE JULY 25, 2009. OWNER MAY CONTACT KENWORTH AT 1-425-828-5440.

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.

Consequence

A FAILURE MAY REDUCE VEHICLE BRAKE PERFORMANCE, INCREASING THE RISK OF A CRASH.

Remedy

Defect

ON CERTAIN TRUCKS, THE AXLE HOUSINGS MAY HAVE BEEN MANUFACTURED WITH STEEL THAT WAS OUT OF SPECIFICATION WHICH COULD RESULT IN A FATIGUE FAILURE OVER TIME.

Consequence

IF A FATIGUE FAILURE OCCURS AND IS LEFT UNATTENDED, THE AXLE MAY LOCK UP OR THE END OF THE AXLE COULD COME OFF, WHICH MAY RESULT IN A VEHICLE CRASH.

Remedy

DEALERS WILL INSPECT AND REPLACE THE AXLES FREE OF CHARGE. THE RECALL BEGAN ON MAY 9, 2007. OWNERS MAY CONTACT KENWORTH AT 425-828-5440 AND PETERBILT AT 1-940-591-4196.

Defect

CERTAIN TRUCKS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS." THE TRAILER LIGHT LINE MAY HAVE BEEN ROUTED USING TOO TIGHT OF A BEND RADIUS. THIS ROUTING METHOD COULD CAUSE THE WIRES WITHIN THE HARNESS PLUG TO BE PULLED AWAY FROM THE CHASSIS PLUG RESULTING IN AN INTERMITTENT OR COMPLETE ELECTRICAL POWER LOSS TO THE TRAILER.

Consequence

SHOULD POWER BE LOST, THE ELECTRICAL CIRCUITS WOULD NOT PROVIDE POWER TO THE ANTILOCK SYSTEM ON THE TOWED VEHICLE INCREASING THE RISK OF A CRASH.

Remedy

DEALERS WILL REROUTE THE LIGHT LINE TO ELIMINATE THE EXCESSIVE BEND RADIUS AND REPLACE ANY PLUG OR HARNESS THAT HAS BEEN DAMAGED FREE OF CHARGE. THE RECALL BEGAN ON APRIL 16, 2007. OWNER MAY CONTACT KENWORTH AT 425-828-5440.

Defect

ON CERTAIN TRUCKS EQUIPPED WITH A TRW TILT/TELESCOPING STEERING COLUMN, THE TILT LOCKING MECHANISM ON THE STEERING COLUMN MAY DISENGAGE. THIS COULD PREVENT THE STEERING COLUMN FROM LOCKING IN TO PREDETERMINED POSITIONS.

Consequence

SHOULD THE LOCKING MECHANISM DISENGAGE, THE TILTING TRAVEL OF THE COLUMN WOULD BE UNRESTRICTED. THIS UNRESTRICTED TRAVEL ALLOWS THE STEERING WHEEL TO IMPACT THE DASH AND COULD LIMIT THE MOVEMENT OF THE STEERING WHEEL POTENTIALLY RESULTING IN DIFFICULTY MANEUVERING THE VEHICLE, INCREASING THE RISK OF A CRASH.

Remedy

DEALERS WILL REPLACE THE TILT LOCKING MECHANISM WITH A REVISED DESIGN THAT INCORPORATES A NEW BRACKET FOR RESTRAINING THE TILTING MECHANISM. THE RECALL BEGAN ON DECEMBER 22, 2006. OWNERS MAY CONTACT KENWORTH AT 1-425-828-5440.
