ON CERTAIN TRUCKS EQUIPPED WITH DANA SPICER INTEGRAL KNUCKLE AND STEER ARM ASSEMBLIES, THE STEER AXLE ASSEMBLIES MAY HAVE A LONGITUDINAL CRACK IN THE STEER ARM.

IF THE CRACK SHOULD PROPAGATE OVER TIME, THE BALL COULD BECOME LOOSE RESULTING IN A LOSS OF STEERING, WHICH COULD RESULT IN A CRASH.

DEALERS WILL INSPECT AND REPLACE THE KNUCKLE AND STEER ARM ASSEMBLIES. OWNER NOTIFICATION BEGAN JANUARY 5, 2004. OWNERS SHOULD CONTACT KENWORTH AT 1-425-828-5440 OR PETERBILT AT 1-940-591-4201.

ON CERTAIN HEAVY DUTY TRUCKS, THE LOCKING TAB THAT LOCKS THE OUTER SPINDLE NUT ONTO THE SPINDLE WAS NOT ENGAGED OR PROPERLY BENT OVER.

FAILURE TO PROPERLY ENGAGE THE LOCKING FEATURE INTO THE NUT COULD CAUSE THE NUT TO LOOSEN WHICH WILL EVENTUALLY CAUSE THE WHEEL BEARING TO OVER HEAT AND FAIL IF UNDETECTED. IF THE LOOSE NUT IS NOT DETECTED, THE OUTER END (TIRE, WHEEL AND HUB ASSEMBLY) COULD BECOME SEPARATED FROM THE VEHICLE, INCREASING THE RISK OF A CRASH.

DEALERS WILL INSPECT THE HUBS TO DETERMINE IF THE LOCKING TABS ARE PROPERLY BENT. IF THE LOCKING TABS ARE NOT BENT, THEN DEALERS WILL INSPECT THE APPROPRIATE COMPONENTS FOR PREMATURE WEAR AND REPLACE SUCH COMPONENTS AS REQUIRED AND PROPERLY SECURE THE RETAINING NUT BY BENDING OVER THE LOCKING TAB. OWNER NOTIFICATION BEGAN SEPTEMBER 17, 2003. OWNERS SHOULD CONTACT KENWORTH AT 1-425-828-5440 OR PETERBILT AT 940-591-4201.

ON CERTAIN TRUCKS EQUIPPED WITH JOST INTERNATIONAL JSK 37U SERIES FIFTH WHEELS, A FATIGUE CRACK CAN DEVELOP IN THE BRACKET PIN WELD UNDER CERTAIN LOADING CONDITIONS.

IF LEFT UNDETECTED OR CORRECTED IT COULD LEAD TO THE SEPARATION OF THE FIFTH WHEEL TOP PLATE FROM ITS MOUNTING STRUCTURE, POSSIBLY RESULTING IN A CRASH.

DEALERS WILL REPLACE THE BRACKET PINS AND REPAIR INSTRUCTIONS FREE OF CHARGE. PETERBILT'S OWNER NOTIFICATION BEGAN JUNE 20, 2003. KENWORTH'S OWNER NOTIFICATION BEGAN JUNE 12, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT PETERBILT AT 940-591-4201 OR KENWORTH 425-828-5440.

ON CERTAIN TRUCKS EQUIPPED WITH MERITOR 15X4 FRONT BRAKES AND DANA E1200 STEER AXLE, THE LEFT BRAKE CANNOT FULLY APPLY OR IT WOULD BECOME STUCK AND NOT RELEASE.

IF THE LEFT BRAKE CANNOT FULLY BE APPLIED OR IF IT WERE TO BECOME STUCK AND NOT RELEASE, THIS COULD AFFECT THE VEHILCE STOPPING DISTANCE AND STABILITY.

DEALERS WILL REPLACE THE "UNHANDED" AUTOMATIC SLACK ADJUSTER WITH A "HANDED" AUTOMATIC SLACK ADJUSTER THAT HAS A SIDE MOUNTED PAWL NUT. OWNER NOTIFICATION BEGAN JANUARY 6, 2004. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE FREMEDY WITHIN A REASONABLE TIME SHOULD CONTACT PETERBILT AT 1-940-591-4201.

ON CERTAIN NON-ABS EQUIPPED TRUCKS, AN AIR HOSE BETWEEN THE TRACTOR PROTECTION VALVE AND THE BACK OF THE CAB BULKHEAD WAS OMITTED.

THE ABSENCE OF THIS AIR HOSE COULD ADVERSELY AFFECT THE DRIVE AXLE BRAKE PERFORMANCE WHILE A TRAILER IS BEING PULLED, RESULTING IN LONGER STOPPING DISTANCES, INCREASING THE RISK OF A CRASH.

PETERBILT WILL INSPECT THE AIR HOSE PLUMBING OF THE DRIVE AXLE BRAKE SYSTEM AND MAKE THE NECESSARY REPAIRS. THE RECALL BEGAN ON FEBRUARY 22, 2007. OWNERS MAY CONTACT PETERBILT AT 1-940-591-4196.
