How to Check Lubricant
Active Transfer Case
A. Fill Plug
B. Drain Plug
To get an accurate reading, the vehicle should be on a
level surface.
If the level is below the bottom of the fill plug hole, you
will need to add some lubricant. Add enough lubricant
to raise the level to the bottom of the fill plug hole.
Use care not to overtighten the plug.

how often to change the lubricant. See
