What's wrong?
The steering wheel attachment bolt on the 2024 Mack Md is the critical fastener that holds the steering wheel to the steering shaft. The steering shaft carries your steering input down to the steering gear, so the bolt has to keep that joint tight every time the wheel is turned.
On affected trucks, the wrong assembly tool was used while installing the steering shaft retention bolt. That created a torque problem: the bolt was tightened with too much or too little force. Without the right clamping force, the bolt can loosen over time and separate from the steering shaft. If that happens, the steering wheel can detach from the shaft.
The driver can have a warning sign before failure. Watch for extra play or looseness in the steering wheel, especially if the wheel feels less firmly connected than normal.
