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 fill plug hole, located on the transfer case, the vehicle will need some lubricant added. Add enough lubricant to raise the level to the bottom of the fill plug hole. A fluid loss could indicate a problem; check and have it repaired, if needed.
What to Use
Refer to Recommended Fluids and Lubricants on page 11‑12 to determine what kind of lubricant to use.
