Defect
Ford Motor Company (Ford) is recalling certain 2021 F-350, F-450, F-550, and F-600 vehicles equipped with dual rear wheels and front wheel hub extenders.

Safety risk
A detached wheel and wheel extender can increase the risk of a crash.
Remedy
Owners are instructed not to drive their vehicles until the torque of the wheel extender nuts can be verified. Dealers will inspect and tighten the front wheel hub extender nuts, free of charge. Owner notification letters were mailed on June 18, 2021. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 21S26.
