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
“Scheduled Maintenance Services” in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you‘ll need to add some lubricant.
If the differential is at operating temperature (warm),
add enough lubricant to raise the level
to the bottom of
the filler plug
hole.
If the differential is cold, add enough lubricant to raise
the level to 1/2 inch (: 12 mm) below the filler plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind
of lubricant to use. See ”Recommended Fluids and
Lubricants” in the Index.
