A. Drain Plug
B. Filler Plug
If the level is below the bottom of the filler plug
hole, located on the transfer case, you’ll need to
add some lubricant. Remove the plug and
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
Refer to the Maintenance Schedule to determine
what kind of lubricant to use. See Recommended
Fluids and Lubricants on page 447.
Front Axle
When to Check and Change Lubricant
It is not necessary to regularly check your front
axle 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.
