Problem 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 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. Risk A detached wheel and wheel extender can increase the risk of a crash. Fix 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.

Two numbers, one recall

Every safety recall carries two identifiers. 21S26 is the number Ford assigned in its own system: it is what appears on the owner letter, on the dealer’s service screen and on the repair order. 21V390000 is the number NHTSA filed the same recall under when the manufacturer reported it, and it is the one every federal record, this site included, is keyed on.

The repair is free by federal law for vehicles up to fifteen years old. Whether one particular vehicle is included is settled by its VIN against the manufacturer’s build list, not by its model year.

Check one specific vehicle

Both lookups check a VIN against the manufacturer’s own list and say whether the repair is still outstanding on that vehicle.
