Official summary
Some 2019-2021 Ranger vehicles may exhibit a shudder/vibration when accelerating from a stop. This may be due to an excessive rear axle pinion angle. To correct the condition, follow the Service Procedure steps to adjust the rear axle pinion angle. This article supersedes TSB 20-2277 to update the vehicle model years affected.

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.
