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.

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.
