What's recalled

Component: Powertrain / transmission (axle assembly)

Ford Motor Company (Ford) is recalling certain 2020-2021 F-350 Super Duty pickup trucks equipped with 6.7L diesel engines and Dana model 275 rear axles. The rear axle housing may not support the load of the pickup truck and deform, which could result in driveshaft separation.

The risk

Driveshaft separation may result in a loss of drive power, or unintended vehicle movement if the vehicle is in park without the parking brake applied, increasing the risk of a crash.

The remedy and its status

Dealers will inspect the axle housing for deformities, and repair or replace the housing, as necessary, free of charge. Owner notification letters were mailed on September 3, 2021. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall 21S31.

Status: NHTSA lists Sep 3, 2021 as the owner-notification date for this campaign.
