Ford Motor Company is recalling approximately 34,939 model year 2020-2021 F-350 Super Duty trucks with a 6.7-liter engine and single rear wheel axle for a rear axle housing spring seat interface weld issue.

The vehicles may experience rear driveline disconnection leading to vibration and/or shaking at highway speeds, and/or shuddering upon acceleration.

A disconnected driveshaft could result in a loss of motive power while the vehicle is being driven or loss of transmission park function if the parking brake is not applied, increasing the risk of a crash.

What to do

Dealers will inspect the rear axle to determine if deformation is present. If the axle is deformed, the axle housing will be replaced. If it is not deformed, the dealer will perform a weld repair on the spring seats.

Owner notifications letters are expected to be mailed the week of August 16, 2021.

Owners may contact customer service at (866) 436-7332. Ford's number for this recall is 21S31.
