Official summary
Some 2017-2019 F-250/F-350 4WD vehicles may exhibit a sustained steering wheel oscillation after hitting rough pavement or an expansion joint above 45 mph (72 km/h). This may be due to excessive lag/lash of the steering linkage damper. To correct the condition, follow the Service Procedure to replace the steering linkage damper.

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.
