2005 Freightliner Classic Xl problems

Defect

DAIMLER TRUCKS IS RECALLING CERTAIN MODEL YEAR 2005-2011 FREIGHTLINER CASCADIA, COLUMBIA, CENTURY, CORONADO, AND CLASSIC XL TRUCKS MANUFACTURED FROM NOVEMBER 1, 2004, THROUGH JUNE 15, 2010 FOR THE RACK AND PINION STEERING SYSTEM. THE LOWER PINION BEARING MAY CORRODE AND FAIL. A FAILED BEARING MAY LEAD TO DAMAGE OF THE SPOOL VALVE SEALS. A DAMAGE SPOOL VALVE SEAL MAY ALLOW HYDRAULIC FLUID TO FLOW TO THE RIGHT OR LEFT TURN PORT INSTEAD OF FLOWING TO THE RETURN PORT.

Consequence

THE STEERING COULD UNEXPECTEDLY TURN LEFT OR RIGHT, MAKING THE VEHICLE MORE DIFFICULT TO CONTROL AND INCREASING THE RISK OF A CRASH.

Remedy

DAIMLER TRUCKS WILL INSPECT THE LOWER BEARING FOR CORROSION. IF CORROSION IS FOUND, THE RACK AND PINION SYSTEM WILL BE REPLACED. IF NO CORROSION IS FOUND, ON THE BEARING, THE BEARING WILL BE PACKED WITH GREASE AND THE RUBBER BELLOWS WILL BE REPLACED WITH SEALANT ADDED BETWEEN THE BELLOWS AND THE RACK HOUSING. AN INTERIM LETTER WAS MAILED IN DECEMBER 2011. OWNERS MAY CONTACT DAIMLER TRUCKS TOLL-FREE AT 1-800-547-0712.

Defect

ON CERTAIN TRUCKS EQUIPPED WITH RACK AND PINION STEERING, THE BALL SOCKET ASSEMBLY AT THE INNER END OF THE DRIVER SIDE TIE ROD MAY BE DAMAGED IN A SHARP TURN. EXCESSIVE TIE ROD ANGLES MAY LOOSEN THE TIE ROD IN THE BALL SOCKET OR DAMAGE THE THREADED TIE ROD SOCKET ATTACHMENT TO THE STEERING RACK ON THE DRIVER SIDE. THE THREADED END OF THE BALL SOCKET ASSEMBLY MAY FRACTURE AND SEPARATE.

Consequence

A FRACTURED TIE ROD ASSEMBLY WILL MAKE THE VEHICLE MORE DIFFICULT TO CONTROL AT HIGHER SPEEDS AND A CRASH MAY OCCUR.

Remedy

DEALERS WILL CHANGE THE FRONT AXLE STEERING STOPS TO PREVENT INTERFERENCE IN THE TIE ROD BALL SOCKET ASSEMBLY AND STEERING COMPONENTS WILL BE REPLACED FREE OF CHARGE. THE RECALL BEGAN ON JULY 8, 2008, AND WILL BE MAILED IN PHASES THROUGH DECEMBER 31, 2008. OWNERS MAY CONTACT FREIGHTLINER AT 1-800-547-0712.

Defect

ON CERTAIN TRUCKS EQUIPPED WITH RACK AND PINION STEERING, THE TIE ROD ARMS MAY HAVE BEEN INCORRECTLY INSTALLED. THE THREADED END OF THE BALL SOCKET ASSEMBLY MAY FRACTURE AND SEPARATE.

Consequence

A FRACTURED TIE ROD ASSEMBLY WILL MAKE THE VEHICLE MORE DIFFICULT TO CONTROL AT HIGHER SPEEDS AND A CRASH MAY OCCUR.

Remedy

DEALERS WILL INSPECT FOR INSTALLATION OF THE STEERING ARMS. STEERING COMPONENTS WILL BE REPLACED ON TRUCKS THAT HAVE INCORRECTLY INSTALLED TIE ROD ARMS. THE RECALL BEGAN ON MAY 1, 2008. OWNER MAY CONTACT FREIGHTLINER AT 1-800-547-0712.

Defect

CERTAIN FREIGHTLINER SCHOOL BUS CHASSIS, HEAVY TRUCKS, AND THOMAS BUILT SCHOOL BUSES MANUFACTURED BETWEEN JULY 2002 AND JULY 3, 2007, EQUIPPED WITH BENDIX SR-7 SPRING BRAKE CONTROL VALVES. THE PARKER SCV BRASS 90 DEGREE SINGLE CHECK VALVES (SCV) WHICH ATTACH TO THE SUPPLY PORT OF A BENDIX SR-7 SPRING BRAKE MODULATING VALVE CAN BREAK APART. PIECES OF THE PARKER SCV CAN BECOME LODGED INSIDE THE SR-7 SPRING BRAKE MODULATING VALVE, POTENTIALLY CAUSING EITHER LEAKAGE OUT OF THE SR-7 VALVE OR PREVENTING AIR FROM PROPERLY EXHAUSTING FROM THE SR-7 VALVE. ALSO, DUE TO A MANUFACTURING DEFECT IN THE INTERNAL RUBBER CHECK VALVE INSIDE THE SR-7 SPRING BRAKE MODULATING VALVES, THE VALVES CAN BECOME DEFORMED AND NOT SEAT PROPERLY.

Consequence

THESE CONDITIONS COULD EITHER RESULT IN LEAKAGE AND CAUSE A DELAY IN THE APPLICATION OF THE SPRING BRAKE WITHOUT WARNING OR POSSIBLY LEAD TO UNINTENDED VEHICLE ROLLAWAY OR BRAKE DRAG WHICH COULD RESULT IN A VEHICLE CRASH, PERSONAL INJURY, OR DEATH.

Remedy

FREIGHTLINER WILL NOTIFY OWNERS AND REPAIR THE VEHICLES FREE OF CHARGE. THE RECALL BEGAN ON JANUARY 11, 2008 TO FREIGHTLINER, STERLING, AND FREIGHTLINER CUSTOM CHASSIS OWNERS; TO THOMAS BUILT BUS OWNERS ON FEBRUARY 1, 2008. OWNERS CAN CONTACT FREIGHTLINER AT 1-800-547-0712.

Defect

ON CERTAIN TRUCKS 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.

Consequence
