## NHTSA's 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.
