In the event that the Anti-lock Brake System (ABS) loses battery and/or ignition power to the controller, the dash warning light for the ABS may not illuminate to warn the driver of the loss of ABS. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems," and 136, "Electronic Stability Control System on Heavy Vehicles."
PACCAR is recalling certain model year 2007-2014 Kenworth T800 and W900 trucks manufactured March 22, 2006, through July 15, 2013 and equipped with Primaax tridem rear suspensions and a pusher and/or tag axle. The affected trucks have brake chambers that take longer to apply or release the brakes than the required time limit. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 121, "Air Brake Systems."
PACCAR IS RECALLING CERTAIN MODEL YEAR 2008-2012 KENWORTH T2000, T660, T700, T800, AND W900, AS WELL AS MODEL YEAR 2009-2012 PETERBILT 365, 367, 384, 386, 387, 388, 389, AND 587 TRUCKS EQUIPPED WITH PACCAR MX ENGINES. THE OIL MODULE CENTRIFUGAL SPINNER FILTER CAP IN THE PACCAR MX ENGINE MAY BECOME LOOSE, POSSIBLY ALLOWING THE CAP TO COME OFF AND ENGINE OIL TO PARTIALLY DISCHARGE FROM THE OIL MODULE ONTO EXHAUST COMPONENTS.
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.
PACCAR IS RECALLING CERTAIN MODEL YEAR 2008-2010 TRUCKS EQUIPPED WITH TRW STEERING SHAFTS. THE CIRCUMFERENTIAL WELD AROUND THE STEERING SHAFT TUBE THAT WELDS THE SPLINED TUBE TO THE NON-SPLINED TUBE MAY BE MISLOCATED. MISLOCATION OF THE CIRCUMFERENTIAL WELD MAY ALLOW THE SPLINED TUBE AND NON-SPLINED TUBE TO ROTATE RELATIVE TO ONE ANOTHER DURING A LOW SPEED, HIGH TORQUE TURN, POSSIBLY RESULTING IN A SEPARATION OF THE TWO TUBES.
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 140 MY 2005, 2007-2009 T800, W900, AND T660 TRUCKS. THE CALIPER MOUNTING FASTENERS ATTACHING THE AIR DISC BRAKE CALIPER ASSEMBLY TO THE TORQUE PLATE MAY HAVE RECEIVED INSUFFICIENT TORQUE DURING THE INSTALLATION PROCESS.

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, THE AXLE HOUSINGS MAY HAVE BEEN MANUFACTURED WITH STEEL THAT WAS OUT OF SPECIFICATION WHICH COULD RESULT IN A FATIGUE FAILURE OVER TIME.
ON CERTAIN TRUCKS, THE WIRING, PARTS, OR TRANSMISSION PROGRAMMING REQUIRED FOR THE AUTO NEUTRAL FEATURE TO FUNCTION AS DESIGNED WERE EITHER NOT INSTALLED, CONNECTED, OR PROGRAMMED PROPERLY.
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.
