Affects Ford F-450 Chassis Cab, F-550 Chassis Cab · 2017 — about 39 vehicles.
The hazard
Certain vehicles equipped with a 6.8L gasoline engine, 4x4 drive, 205” wheel base and 4.88 axle ratio may experience a driveline vibration caused by a powertrain resonance at speeds above 120 km/h. Continued operation of a vehicle at these speeds could result in a resonance frequency that may fracture transmission and/or driveline components. If the transmission and or driveline components were to fracture, it could result in a loss of motive power while the vehicle is in motion, or unintended vehicle movement in Park if the parking brake is not applied, which would increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace the two-piece driveshaft with a new three-piece driveshaft and two center bearing brackets.
