What's recalled
Component: Powertrain / transmission (axle hubs)
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.

The risk
A detached wheel and wheel extender can increase the risk of a crash.

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.
Status: NHTSA lists Jun 18, 2021 as the owner-notification date for this campaign.
