Official summary
Some 2019-2023 Ranger (non-Tremor) vehicles may exhibit a shudder/vibration when accelerating. This may be due to an excessive rear axle pinion angle (rear wheel drive (RWD) vehicles) or the pinion and driveshaft assemblies (four-wheel drive (4WD) non-Tremor vehicles). To correct the condition, follow the Service Procedure steps to adjust the rear axle pinion angle on 4x2 vehicles or replace the rear axle pinion and driveshaft on 4x4 non-Tremor vehicles.
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.
