add lubricant, if needed, to

Rear Axle Lubricant
It is not necessary to regularly
check the fluid unless you suspect
there is a leak in the system or you
hear an unusual noise.
Fluid loss in this system could
indicate a problem. Have the
system inspected.
Axle assemblies are filled by
volume of fluid rather than filled to
reach a certain level. Readings will
vary depending on how long the
vehicle has been stationary.
Remember that the rear axle
assembly must be supported to
get a true reading.
See the "Recommended Fluids and
Lubricants" chart later in this
section to determine what kind of
fluid to use.
To check the fluid level:
Park the vehicle on a level
surface and apply the parking
brake.
Turn off the engine.
Check the level of the lubricant by
removing the plug.
• Two-Wheel Drive Vehicles
The proper level is 15 mm to
40 mm below the bottom of
the filler plug hole.
