Ford recalls nearly 35,000 trucks that may have weld problems which disconnect the driveshafts. July 19, 2021 — Ford is recalling 2020-2021 Ford F-350 Super Duty vehicles with 6.7-liter engines and single rear wheel axles for weld problems with the rear axle housing spring seat interfaces. Nearly 35,000 trucks are affected by the recall of F-350s built in Kentucky between August 6, 2020, and May 15, 2021. Ford says the rear driveshaft could disconnect, a problem that will cause a loss of motive power and a loss of PARK even with the transmission shifted into PARK. The F-350 Super Duty could also roll away if the parking brake isn't engaged. A Ford truck driver may notice shaking and vibration while driving highway speeds or a shuddering when accelerating. Ford says it is not aware of any crashes or injuries related to the F-350 Super Duty problem. Ford will mail recall notices the week of August 16, 2021.
