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, located on the rear axle, you’ll need to add
some lubricant. Add enough lubricant to raise
the level to the bottom of the filler plug hole.
What to Use
Refer to the Maintenance Schedule to determine
what kind of lubricant to use. See Part C:
Recommended Fluids and Lubricants on page 397.
Rear Axle Shift Motor
When to Check and Change Fluid
If you have an optional air-shift two-speed,
controlled traction, or locking differential type rear
axle, a good time to check the fluid level in the axle
shift motor is when the rear axle lubricant is
checked.
How to Check Fluid
Remove the plug on the front plate of the axle shift
motor, add enough fluid to raise the level to the
bottom of the filler plug hole, then replace the plug.
What to Use
Refer to your Maintenance Schedule to determine
what kind of lubricant to use. See Part C:
Recommended Fluids and Lubricants on page 397.
