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 (Gasoline
Engine) on page 400.
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 3/8 inch (10 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 Recommended
Fluids and Lubricants on page 410.
