Rear Axle
When to Check and Change Lubricant
It is not necessary to regularly check rear axle 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.
The proper level is from 0 to 3/8 inch (0 mm to 10 mm)
below the bottom of the filler plug hole, located on
the rear axle.
What to Use
See Recommended Fluids and Lubricants on page 6-12
to determine which kind of lubricant to use.
