Ford is recalling certain 2020-2012 F-350 Super Duty trucks equipped with a 6.7-liter engine and single rear wheel axle over concerns of a possible driveline disconnection.

A weld issue in the rear axle housing spring seat interface in roughly 35,000 trucks could lead to a driveline disconnection.

Customers in affected vehicles may experience vibration and/or shaking while driving at highway speeds, and/or shuddering upon acceleration. In the event of a disconnected driveshaft, customers may experience loss of motive power while driving or loss of transmission park function if the parking brake is not applied, increasing the risk of a crash.

Affected vehicles were built at Kentucky Truck Plant between Aug. 6, 2020 and May 15, 2021. 

Ford is not aware of any accidents or injuries related to this condition.

Owner notifications will begin the week of Aug. 16. Dealers will inspect rear axle to determine if deformation is present. If the axle is deformed, the axle housing will be replaced. If axle is not deformed, the dealer will perform a weld repair on the spring seats. The Ford reference number for this recall is 21S31.
