What's wrong?
The steering gear in the 2021-2022 Mack trucks covered by recall 22V401 is the heavy-duty part that turns steering wheel input into movement at the wheels. When the driver turns the wheel, the gear uses internal recirculating balls to reduce friction and help carry the load as the steering system moves.
On affected Mack trucks, the steering gear was assembled with fewer recirculating balls than required. With too few balls inside the gear, the load is not supported the way the gear was designed to handle it. That stress can cause the gear to fracture, leaving the steering system unable to transmit the driver's input normally.
There is no warning sign before failure. The driver does not get an audible alert or a warning light, so a truck that feels normal before the trip still needs the recall repair if its VIN is included.
