FREIGHTLINER LLC: Safety Recalls in 2007

ON CERTAIN TRUCKS EQUIPPED WITH CATERPILLAR EPA07 C155 ENGINES, THE EXTENSION PIPES ATTACHED TO THE AFTERTREATMENT REGENERATION DEVICE MAY DEVELOP A CRACK OR HOLE AND HEAT OR FLAME MAY ESCAPE DURING A REGENERATION OF THE DIESEL PARTICULATE FILTER.

ON CERTAIN TRUCKS EQUIPPED WITH TRW STEERING GEARS, MODELS TAS85 AND RCS85, THESE STEERING GEARS CONTAIN POTENTIALLY DEFECTIVE SECTOR SHAFTS WITH AN INCORRECT GEAR TOOTH WHICH MAY INTERFERE WITH THE RACK-PISTON TEETH, RESULTING IN A STICK OR BIND CONDITION.

ON CERTAIN HEAVY DUTY TRUCKS BUILT WITH SISU FR2P-21, SISU FR2P-26, SISU FR3P-33, OR SISU FR3P-48 REAR AXLES, A COUNTER-BORE MACHINED IN BOTH ENDS OF THE WORM WHEEL OPENING OF THE SLACK ADJUSTER HOUSING REDUCES MATERIAL THICKNESS BETWEEN THE WORM WHEEL OPENING AND THE WORM SHAFT OPENING. UNDER NORMAL SERVICE A CRACK MAY DEVELOP IN THIS AREA RENDERING THE SLACK ADJUSTER INOPERABLE AND REDUCING BRAKE EFFECTIVENESS.

ON CERTAIN MOTOR HOME CHASSIS BUILT USING INLINE POWER STEERING FILTERS, PART NO. 14-16829-000, THE FILTER CAN PLUG DUE TO FAILURE OF THE SCREEN ADHESION TO THE FILTER HOUSING CAUSING A RISE IN RETURN LINE PRESSURE. THIS CAN LEAD TO HOSE SEPARATION FROM THE FILTER OR STEERING GEAR FITTING RESULTING IN A SUDDEN LOSS OF STEERING FLUID AND POWER ASSIST.

CERTAIN 2001 THROUGH 2008 THOMAS BUILT FS-56, ER, MVP ER, HDX, AND MVP EF SCHOOL BUSES MANUFACTURED FROM OCTOBER 23, 2000, THROUGH JANUARY 24, 2006, EQUIPPED WITH TYCO PC BOARD AND TYPE II AUTO RESET CIRCUIT BREAKERS. TYPE II AUTO RESET CIRCUIT BREAKER TEMPERATURES MAY EXCEED THE RATING OF THE TYCO PC BOARD CAUSING THE BOARDS TO MELT POTENTIALLY RESULTING IN A VEHICLE FIRE.

ON CERTAIN TRUCKS, THE WIPER MOTOR GROUND WIRE WAS OMITTED IN A NEW HARNESS DESIGN. THE WIPER MOTOR MAY NOT OPERATE OR MAY FUNCTION INTERMITTENTLY.

ON CERTAIN TRUCK-TRACTORS EQUIPPED WITH HOLLAND SIMPLEX SE OR SE II FIFTH WHEELS, THE LATCH LEVER PIVOT BOLT ASSEMBLY MAY HAVE BEEN OVER-TIGHTENED WHICH COULD DISTORT THE PIVOT BOLT SPACER SLEEVE. CORROSION OR CONTAMINATES IN THE PIVOT MAY CAUSE IT TO BIND AND PREVENT THE FIFTH WHEEL JAW FROM LATCHING SECURELY AROUND THE TRAILER KING PIN.

CERTAIN THOMAS BUILT SCHOOL BUSES MANUFACTURED BETWEEN MARCH 8, 2006, AND AUGUST 10, 2007, EQUIPPED WITH ONE OR MORE "PRO LO ROOF HATCH" OPTION NUMBERS D107307001, D107307002, OR D107307003. RETROREFLECTIVE TAPE WAS NOT INSTALLED AROUND THE PERIMETER OF THE ROOF MOUNTED EMERGENCY EXIT HATCH. THESE BUSES FAIL TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 217, BUS EMERGENCY EXITS AND WINDOW RETENTION AND RELEASE.

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.

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.

ON CERTAIN SCHOOL BUS AND MOTOR HOME CHASSIS, IMPROPER PINCH BOLT INSTALLATION MAY RESULT IN DECOUPLING OF THE STEERING SHAFT AND A LOSS OF STEERING.

ON CERTAIN TRUCKS BUILT WITH A TRW GLOBAL ADJUSTABLE UPPER STEERING COLUMN, TWO UPPER TILT PLATE BOLTS MAY LOOSEN WITH USE AND FALL OUT. THESE FASTENERS HOLD THE UPPER COLUMN ASSEMBLY IN PLACE. THE STEERING COLUMN PIVOT MAY FRACTURE IF THE BOLTS ARE MISSING WHEN AN EXCESSIVE FORCE IS APPLIED TO THE STEERING WHEEL.

CERTAIN MOTOR HOME CHASSIS EQUIPPED WITH ZF MODEL 8018 STEERING GEARS MAY HAVE BEEN ASSEMBLED WITH THE INCORRECT RECIRCULATING BALL SPACER. THIS COULD POTENTIALLY ALLOW THE RECIRCULATING BALLS TO ESCAPE FROM THE RECIRCULATING BALL CIRCUIT RESULTING IN A LOSS OF STEERING.

ON CERTAIN TRUCKS, A MANUFACTURING ERROR IN THE FUEL-WATER SEPARATOR PREHEATER THERMOSWITCH MAY PREVENT THE FUEL PREHEATER FROM TURNING OFF IF THE IGNITION IS LEFT ON. IF THE IGNITION SWITCH IS LEFT ON WHEN FUEL IS ADDED TO THE FUEL- WATER SEPARATOR AT THE FACTORY OR DURING A FILTER ELEMENT CHANGE, A SMALL FLAME MAY OCCUR INSIDE THE FILTER COVER.

ON CERTAIN TRUCKS BUILT WITH AXILOK REAR WHEEL SPINDLE NUTS, THE NUTS MAY HAVE BEEN IMPROPERLY INSTALLED, WITH ONE OR BOTH LOCKING CLIP TABS NOT PROPERLY ENGAGED OR DAMAGED.

ON CERTAIN TRUCKS EQUIPPED WITH TUFTRAC REAR SUSPENSIONS, THE CENTER CASTING BRACKETS MAY BE OUT OF SPECIFICATION. AN OUT OF SQUARE CASTING MAY HAVE UNACCEPTABLE STRESS IN THE BRACKET WHEN IT IS INSTALLED AND MAY CAUSE IT TO CRACK IN SERVICE.

ON CERTAIN MOTOR HOMES BUILT WITH CUMMINS ISL CM850 DIESEL ENGINES, THE CONNECTING ROD CONTAINS A MACHINING DEFECT IN THE WRIST PIN BUSHING OF THE ROD THAT COULD CAUSE A SEIZURE OF THE PISTON PIN.

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.
