Recall History (13 recalls)

05V543000Dec 2005

STEERING

ON CERTAIN TRUCKS EQUIPPED WITH THE BENDIX ELECTRONIC STABILITY CONTROL (ESP) SYSTEM, THE SYSTEM USES MULTIPLE SENSORS AND AN ELECTRONIC CONTROL UNIT (ECU) TO CONTROL VEHICLE UNDER STEER, OVER-STEER, AND ROLLOVER SITUATIONS. THE SYSTEM RELIES ON VEHICLE SENSORS TO BE FUNCTIONING AND ALIGNED PROPERLY. THE STEERING ANGLE SENSOR HAS THE POTENTIAL TO BE MISALIGNED WITH THE STEERING COLUMN SHAFT, THEREBY PROVIDING INCORRECT INFORMATION TO THE BENDIX ECU.

TRAILER HITCHES:FIFTH WHEEL ASSEMBLY

ON CERTAIN TRUCKS, AN RA529 KING PIN RELEASE AIR VALVE WAS MANUFACTURED WITH THE INTERNAL SPOOL INSTALLED BACKWARDS. THIS RESULTS IN THE AIR OPTION OF THE KING PIN RELEASE SYSTEM BEING INOPERABLE. TO CORRECT THIS SITUATION, THE VEHICLE'S AIR LINES WERE REVERSED RATHER THAN REPLACING THE VALVE.

SERVICE BRAKES, AIR

CERTAIN TRUCKS FAIL TO COMPLY WITH THE BRAKE TIMING REGULATORY REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS." THE BRAKE VALVE WAS MOVED TO THE OPPOSITE RAIL, INCREASING THE LENGTH OF THE AIR LINE, WHICH IN TURN INCREASED THE WHEELBASE REQUIRING A DUAL RELAY VALVE SYSTEM.
