Rear Axle
When to Check Lubricant
It is not necessary to regularly check rear axle uid
unless you suspect there is a leak or you hear an
unusual noise. A uid loss could indicate a problem.
Have it inspected and repaired.
All axle assemblies are lled by volume of uid during
production. They are not lled to reach a certain
level. When checking the uid level on any axle,
variations in the readings can be caused by factory ll
differences between the minimum and the maximum
uid volume. Also, if a vehicle has just been driven
before checking the uid level, it may appear lower than
normal because uid has traveled out along the axle
tubes and has not drained back to the sump area.
Therefore, a reading taken ve minutes after the vehicle
has been driven will appear to have a lower uid level
than a vehicle that has been stationary for an hour
or two. Remember that the rear axle assembly must be
supported to get a true reading.
How to Check Lubricant
To get an accurate reading, the vehicle should be on a
level surface.
When the differential is cold, the proper level is from
5/8 inch to 1-5/8 inch (15 mm to 40 mm) below the
bottom of the ller plug hole, located on the rear axle.
Add only enough uid to reach the proper level.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. SeeRecommended Fluids
and Lubricants on page 6-12.

Front Axle
When to Check and Change Lubricant
It is not necessary to regularly check front axle uid
unless you suspect there is a leak or you hear an
unusual noise. A uid 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.When the differential is cold, the proper level is from
about 1/4 inch (6 mm) to about 3/8 inch (10 mm) below
the ller plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. SeeRecommended Fluids
and Lubricants on page 6-12.
