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.
