Ford Motor Company is recalling 17,616 model year 2021 F-350s, F-450s, F-550s and F-600s with dual rear wheels and front wheel hub extenders.
The front wheel hub extenders may be improperly attached to the front rotor hub assemblies, which could result in separation of the wheels and wheel extenders from the vehicle.
A detached wheel and wheel extender can increase the risk of a crash.
What to do
Dealers will inspect and tighten the front wheel hub extender nuts, free of charge.
Owners should not drive their vehicles until the torque of the wheel extender nuts can be verified.
