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 ller plug
hole, you’ll need to add some lubricant. Add
enough lubricant to raise the level to the bottom of
the ller plug hole, located on the transfer case.
What to Use
Refer to the Maintenance Schedule to determine
what kind of lubricant to use. SeeRecommended
Fluids and Lubricants on page 449.
