often to check the lubricant and when to change it.

If the level is below the bottom of the filler plug hole,
located on the differential, you will need to add
some lubricant. Add enough lubricant to raise the
level to the bottom of the filler plug hole. A fluid loss
could indicate a problem; check and have it repaired,
if needed.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. See Recommended Fluids
and Lubricants on page 6-11.
