Official summary
Service news article - Are you looking at what seems to be a rear differential axle seal or pinion seal leak? Something to keep in mind: The actual culprit may be something loose or damaged above it. A loose or damaged fluid pressure sensor will drip rear differential fluid onto the axle seal. A loose fluid pressure check port will drip that fluid onto the pinion seal.

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.
