What's wrong?
The front steer axle on a 2015 Mack Pinnacle (Cxu) is the heavy front suspension part that supports the truck's front end and carries steering loads. The axle beam connects the front wheel ends to the suspension, keeps the wheels aligned, and has to stay strong while the driver steers, brakes, and carries load.
On these trucks, the Meritor FF967 Non-Drive Front Steer axle missed a heat-treating step during manufacturing. Heat treatment hardens and strengthens the steel after forging and machining. Without that step, the axle beam has less strength than designed. A service interruption at the heat-treat equipment left no later check to confirm that the process was completed, so the affected axle beams were built into trucks.
The warning sign is a change in handling. The driver can feel the truck become harder to control, and the vehicle can become inoperable. If the axle beam fractures, vehicle control can be lost, and the crash risk rises.
