VEHICLE DESCRIPTION: CERTAIN VEHICLES HAVING AN INTENDED SERVICE CODE OF "FIRE SERVICE" AND EITHER TYPE 24 OR LARGER FRONT BRAKE CHAMBERS OR TYPE 36 REAR BRAKE CHAMBERS FAIL TO COMPLY WITH REQUIREMENTS OF FMVSS NO. 121, "AIR BRAKE SYSTEMS." THESE VEHICLES WERE BUILT WITH A COMBINED AIR RESERVOIR VOLUME LESS THAN 12 TIMES THE COMBINED VOLUME OF ALL SERVICE CHAMBERS.

UNUSUALLY FREQUENT APPLICATIONS OF THE AIR BRAKES COULD DEPLETE THE AVAILABLE AIR SUPPLY MORE QUICKLY THAN EXPECTED.

DEALERS WILL INSTALL AN ADDITIONAL AIR TANK ON CHASSIS WITH A SINGLE REAR AXLE. ON TANDEM REAR AXLE CHASSIS, DEALER WILL REPLACE AN EXISTING AIR TANK WITH A LARGER AIR TANK. OWNER NOTIFICATION BEGAN JULY 16, 2001. 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 KENWORTH AT 1-425-828-5000.

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH 10,000 OR 12,000 POUND DANA FRONT AXLES. A CONDITION CALLED BRAKE "SPRAG", WHICH IS CHARACTERIZED BY A NOISE AT THE END OF AN APPLIED STOP, CAN DEVELOP IN THE BRAKE SYSTEM. THIS NOISE IS THE RESULT OF A PULSATION OF THE BRAKE LINING WITH THE BRAKE DRUM DURING BRAKE APPLICATION. THESE NOISE VIBRATIONS OCCUR AT THE RESONANT FREQUENCY OF THE FRONT AXLE CROSS-TUBE ASSEMBLY AND CAUSE UNUSUALLY HIGH STRAIN FORCES IN THE THREADED PORTION OF THE TIE ROD ENDS THAT ARE CONNECTED TO THE CROSS-TUBE.

FAILURE OF THE TIE ROD END CAN CAUSE LOSS OF STEERING CONTROL AND POSSIBLY RESULT IN A VEHICLE CRASH.

DEALERS WILL REPLACE THE BRAKE LINING ON THE FRONT AXLE OF EACH VEHICLE WITH A LINING MADE OF A DIFFERENT COMPOSITION. IN ADDITION, THE TIE ROD ENDS WILL BE REPLACED FREE OF CHARGE. OWNER NOTIFICATION BEGAN OCTOBER 12, 2001. 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 KENWORTH AT 1-425-828-5000.

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH TRW TIE ROD ENDS ON CERTAIN MERITOR AXLES. THE TIE ROD AND DRAG LINK BALL STUD ENDS CONTAIN BEARINGS THAT ARE BELOW THE SPECIFIED CASE DEPTH AND/OR HARDNESS.

THIS CAN LEAD TO PREMATURE WEAR WITH POSSIBLE SEPARATION OF THE BALL STUD FROM THE SOCKET, INCREASING THE RISK OF LOSS OF CONTROL OF THE VEHICLE.

DEALERS WILL REMOVE AND REPLACE ALL AFFECTED TIE RODS AND DRAG LINKS WITH DIFFERENT DESIGNED ENDS. OWNER NOTIFICATION BEGAN OCTOBER 24, 2001. 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 1-940-591-4000 OR KENWORTH AT 1-425-828-5000.

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH EATON AUTOSHIFT GEN II TRANSMISSION ASSEMBLIES. DUE TO A SOFTWARE PROBLEM IN THE TRANSMISSION ASSEMBLIES, THE TRANSMISSION WILL SELECT THE WRONG GEAR.

DEALERS WILL REPLACE THE AUTOSHIFT TRANSMISSIONS. EATON PERFORMED THE CAMPAIGN FOR THE KENWORTH PORTION. HOWEVER PETERBILT WILL BE CONDUCTING THEIR OWN CAMPAIGN.

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH CHALMERS 1000 SERIES AND 800 SERIES SUSPENSION KITS. THESE SUSPENSION KITS MAY HAVE INSUFFICIENT PENETRATION OF THE WELD ATTACHING THE TORQUE ROD EYE TO THE TORQUE ROD TUBE.
