Plain-English summary

Ford Motor Company is recalling certain 2021 Ford F-350 SD, F-450 SD, F-550 SD, and F-600 SD vehicles equipped with dual rear wheels and front wheel hub extenders. The front wheel hub extenders may be improperly attached to the front rotor hub assemblies.

If the wheel hub extenders become detached, the wheels and wheel extenders could separate from the vehicle. A detached wheel can increase the risk of a crash.

Dealers will inspect and tighten the front wheel hub extender nuts free of charge. Owner notification letters were mailed on June 18, 2021.
