What is wrong

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.

Risk

Vehicles 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.

Remedy

Owner notification is being conducted by neway anchorlok. Dealers will inspect and replace all suspension suspension beams with suspension beams containing appropriate shafts.

What is wrong

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.

In 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.

Remedy

Dealers will modify the main cab wiring harness routing.
