Official summary
Some 2021-2022 F-250 vehicles equipped with a 6R100 transmission, four-wheel drive (4WD), and built on 01-Feb-2021 and through 16-May-2022 may exhibit a metallic grinding noise from the rear of the vehicle under light acceleration between 23-33 mph (37-53 km/h). The noise is most prevalent in 3rd and 4th gear when the vehicle is warm. This may be due to normal driveline noise transmitting through the driveshaft. To correct the condition, follow the Service Procedure to replace the rear axle drive pinion flange, rear pinion seal, and reprogram the powertrain control module (PCM).

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
