Transfer Case

When to Check Lubricant

It is not necessary to regularly check transfer case ﬂuid

unless you suspect there is a leak or you hear an

unusual noise. A ﬂuid loss could indicate a problem.

Have it inspected and repaired.

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’ll need to add some lubricant. Add enough lubricant

to raise the level to the bottom of the ﬁller plug hole.

Use care not to overtighten the plug.
