Front Axle
When to Check and Change
Lubricant
It is not necessary to regularly
check front axle fluid unless there is
a leak suspected or an unusual
noise is heard. 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. A. Fill Plug
B. Drain Plug
. When the differential is cold, add
enough lubricant to raise the
level from 0 mm (0 in) to 3.2 mm
(1/8 in) below the fill plug hole.
. When the differential is at
operating temperature (warm),
add enough lubricant to raise the
level to the bottom of the fill
plug hole.
What to Use
Refer to Recommended Fluids and
Lubricants on page 11‑11 to
determine what kind of lubricant
to use.
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.
