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,
you may need to add some lubricant.
When the differential is cold, add enough lubricant to
raise the level to
1/2 inch (12 mm) below the filler plug
hole.
When the differential is at operating temperature
(warm), add enough lubricant to raise the level to the
bottom
of the filler plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind
of lubricant to use. See Part D: Recommended
Fluids
and Lubricants on page 6-1 7.
