When to Check Lubricant
It is not necessary to regularly check fluid unless you
suspect there is a leak or you hear an unusual noise.
A fluid loss could indicate a problem. Have it inspected
and repaired.
How to Check Lubricant
To get an accurate reading,
the vehicle should be on a
level surface.
If the level is below the bottom of the filler plug hole,
located on the transfer case, you’ll need to add some
lubricant. Add enough lubricant to raise the level to the
bottom of the filler plug hole. Use care not to overtighten
the plug.
What to Use
To determine what kind of lubricant to use, see
Recommended Fluids and Lubricants on page 6-12.
