Notes:

A faulty seal lets ATF or gear oil escape into the
converter housing via the center vent of the
shaft seal (between the two sealing lips).
In addition, a faulty seal can let ATF escape
into the center differential. It over-fills and oil
escapes at the differential vent.

Removing

- Loosen bolt drive axle/wheel hub while the
vehicle is still standing on its wheels.

- Remove front wheels.

- Remove heat shield for right drive axle.
