The problem
Ford Motor Company (Ford) is recalling certain 2020 F-550 and 2021 E-350 and E-450 vehicles. The rear axle differential fluid may be below the minimum level, possibly resulting in a failure of the rear axle assembly and driveshaft separation.
The risk
If the driveshaft separates, there may be a loss of drive, increasing the risk of crash. Additionally, if the parking brake is not applied, unintended vehicle movement can occur and increase the risk of injury or crash.
The fix
Ford will notify owners, and dealers will inspect the rear axle differential fluid level and adjust it, or replace the rear axle as necessary, free of charge. The recall began March 19, 2020. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 20S09.
