When to Check and Change
Lubricant
Refer to the Maintenance Schedule
to determine how often to check the
lubricant and when to change it.
See Maintenance Schedule on
page 11‑3.
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 fill plug hole, some lubricant
may need to be added.
When the differential is cold, add
enough lubricant to raise the level
to 10 mm (3/8 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 11‑12 to
determine what kind of lubricant
to use.
