What's wrong?
The front drive axle on these 2015-2016 Pierce Enforcer, Arrow Xt, Velocity, and Saber vehicles sends engine power to the front wheels when the drivetrain calls for it. The flange yoke is a driveline connection point on that axle, and its hex nuts clamp the yoke tightly in place so the rotating parts stay aligned under load.
On affected vehicles, the hex nuts on the flange yoke were not tightened to the required torque. Pierce traced the issue to defective certified torque equipment at Marmon-Herrington, the supplier of the MT-22 front drive axle. If the nuts are loose, the connection loses clamping force and the driveline can vibrate instead of staying firmly held.
A driver can notice driveline vibration while the vehicle is moving. A visual inspection can also show loose or missing nuts, which is the warning sign to have the axle hardware checked before the vehicle stays in service.

What's the safety risk?
Loose hex nuts can let the driveshaft disconnect from the drive axle, causing loss of propulsion and increasing crash risk. Driveline vibration or visible loose or missing nuts are warning signs; treat them as a reason to stop using the vehicle and call a Pierce dealer. Repair is free at any franchised Pierce dealer.
