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 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 527.
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.
All axle assemblies are filled by volume of fluid
during production. They are not filled to reach
a certain level. When checking the fluid level on
any axle, variations in the readings can be caused
by factory fill differences between the minimum
and the maximum fluid volume. Also, if a vehicle
has just been driven before checking the fluid
level, it may appear lower than normal because
fluid has traveled out along the axle tubes
and has not drained back to the sump area.
