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