Official summary
Some 2021-2023 Explorer Timberline vehicles may exhibit differential fluid venting from the differential fluid vent. The customer may notice differential fluid pooling below the vehicle or saturating the wheel well liner. This may be due to the differential vent tube not having enough positive incline. To correct the condition, follow the Service Procedure to replace the differential vent tube.

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.
