Front 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 indi-
cate a problem. Have the system
inspected.
As it is difficult to perform the
procedure yourself, have the fluid
level checked or changed by your
dealer or service centre.
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 indi-
cate a problem. Have the system
inspected.
See the "Recommended Fluids and
Lubricants" chart later in this
section to determine what kind of
fluid to use.
To check the fluid level:
1. Park the vehicle on a level sur-
face and apply the park brake.
2. Turn off the engine.
3. Remove the filler plug.
The proper fluid level is
0 mm to 10 mm (0 to 3/8
inch) below the bottom of the
filler plug hole located on the
rear axle.
4. Add lubricant, if needed, to
bring the level up to the bot-
tom of the filler plug hole.
5. Re-install the filler plug.
