9-30 Vehicle Care
All-Wheel Drive
If your vehicle is equipped with
all-wheel-drive, this is an additional
system that needs lubrication.
Transfer Case
When to Check Lubricant
It is not necessary to regularly
check the transfer case 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
A. Drain Plug
B. Fill Plug
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
Refer to the Maintenance Schedule
to determine what kind of lubricant
to use. See Recommended Fluids
and Lubricants on page 10‑7.
Rear Axle
When to Check Lubricant
It is not necessary to regularly
check rear 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.
