How to Check Lubricant
If you have an all-wheel-drive vehicle, be sure to
perform the lubricant checks described in this section.
However, they have two additional systems that
need lubrication.
Transfer Case (Power Transfer Unit)
When to Check Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant. See Part C: Periodic
Maintenance Inspections on page 6- 15.
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'll need to add some lubricant. 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- 17.
