THE EQUALIZING BEAM SHAFT OF THE TANDEM AXLE SUSPENSION WERE MANUFACTURED FROM AS-ROLLED SAE4140 STEEL RATHER THAN THE SPECIFIED ANNEALED SAE4140. THESE SHAFTS CAN FRACTURE INSIDE THE BEAM AT THE TOE OF THE WELD.

RiskVEHICLES ARE SUBJECT TO VEHICLE TILT AND POSSIBLE ROLLOVER IN THE EVENT THAT BOTH EQUALIZING BEAMS, ON THE SAME SIDE OF THE VEHICLE, EXPERIENCE A SIMULTANEOUS SHAFT FAILURE. AFFECTED SUSPENSIONS CAN ALSO DROP AND CONTACT THE ROAD SURFACE GENERATING SPARKS WHICH COULD IGNITE FLAMMABLE MATERIAL.

FixOWNER NOTIFICATION IS BEING CONDUCTED BY NEWAY ANCHORLOK. DEALERS WILL INSPECT AND REPLACE ALL SUSPENSION SUSPENSION BEAMS WITH SUSPENSION BEAMS CONTAINING APPROPRIATE SHAFTS.

THE WINDSHIELD WIPER ARM CAN INTERFERE WITH THE MAIN CAB DASH HARNESS WHICH PASSES BEHIND THE CENTER DASH SECTION. THE WIPER ARM CAN WEAR THROUGH ONE OR MORE OF THE WIRES IN THE HARNESS AND CAUSE A SHORT CIRCUIT.

RiskIN ELECTRONIC ENGINES (CATERPILLAR ONLY) OR DDA ENGINES, THE ENGINE WOULD STOP. IF THE ENGINE WERE TO STOP SUDDENLY WHEN THE VEHICLE WAS TRAVELING AT A HIGH RATE OF SPEED AND MANEUVERING THROUGH TRAFFIC, THERE WOULD BE A POTENTIAL FOR A VEHICLE ACCIDENT.

FixDEALERS WILL MODIFY THE MAIN CAB WIRING HARNESS ROUTING.

THESE TRUCKS WERE NOT BUILT WITH INVERSION VALVES DUE TO A PROGRAMMING ERROR. THE INVERSION VALVE PROVIDES MODULATED SPRING BRAKE APPLICATION DURING EMERGENCY BRAKING WHEN THE "A" PORTION OF THE AIR BRAKE SYSTEM HAS FAILED.

RiskIN AN EMERGENCY SITUATION, THE BRAKE SYSTEM WOULD NOT WORK PROPERLY INCREASING THE POTENTIAL FOR A VEHICLE ACCIDENT.

FixDEALERS WILL INSTALL AN INVERSION VALVE IN THESE VEHICLES.
