DAIMLER TRUCKS IS RECALLING 900 MY 2008 FREIGHTLINER ARGOSY, ARGOSY RHD, CASCADIA, COLUMBIA, CENTURY ST, CORONADO, STERLING ACTERRA, L-LINE AND WESTERN STAR 4900 TRUCKS EQUIPPED WITH BENDIX MV-3 DASH CONTROL VALVES. THE MOLDED VALVE BODY HAS AN INCORRECT CORE PIN IN THE INJECTION MOLD CAUSING THE VALVE BODY TO BE OVERSIZED IN THE DOUBLE CHECK VALVE AREA. THIS CONDITION CAN ALLOW THE RUBBER DOUBLE CHECK VALVE TO BECOME LODGED IN THE BODY OPENING UNDER CERTAIN CIRCUMSTANCES.

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 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.

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 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.

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.

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.
