SSM 50900 - 2020-2022 Explorer/Aviator/Police Interceptor Utility - Noise,
Smell, And/Or Leak From The Rear Of Vehicle - Rear Axle Differential Venting
Fluid
Some 2020-2022 Explorer/Aviator/Police Interceptor Utility vehicles may exhibit a rear differential
that is venting rear axle fluid. This may result in a noise, smell, or leak noticed by the customer.
Inspect the rear of the vehicle for signs of rear differential fluid venting in the right rear wheel well (oil
staining in the wheel well liner and/or oil residue on the wheel end assembly below) or leaking from
the rear differential. If signs of fluid leaks are found from any seals, repair as necessary. Refer to
Workshop Manual (WSM), Section 205-02. If no seal leaks are found but fluid is venting, drain the
rear differential and re-fill with fresh rear differential fluid. Remove the vent tube and use
compressed air to verify that the fluid vent tube is clear. Reinstall the vent tube. Engineering is
investigating, monitor OASIS for updates.
