11-24 Pretrip inspection and maintenance
4.1 Checking axle oil level
1. Remove the fill plug and make sure that the
oil is level with the bottom of the fill opening.
2. If the level is too low, add oil through the fill hole
until it is at the level of the fill opening.
CAUTION
Add oil of the same grade and viscosity as the
original axle oil fill. Mixing oil can damage the
differential gears.
3. Install the fill plug.
4.2 Changing axle oil
1. Remove the fill plug and magnetic drain plug
. Drain the oil while the axle is still warm.
Catch the used axle oil in a suitable container
and dispose of it properly.
NOTE:
After operation, let the transmission cool for about
30 minutes before draining the oil. The oil will drain
more quickly while it is still warm.
2. Clean the magnetic drain plug before installing
it. Use a piece of key stock, or any other conve-
nient steel slug, to short the two magnetic poles
and divert the magnetic field.
3. Add oil through the fill hole until it is at the level
of the fill opening.
4. Install the fill plug.
Fill plug torque 72 to 87 lbf·ft (98 to 115 N·m)
WARNING
Axle oil is extremely hot immediately after
vehicle operation. Hot axle oil can cause
burns.
Drain plug torque 72 to 87 lbf·ft (98 to 115 N·m)
Fill plug torque 72 to 87 lbf·ft (98 to 115 N·m)
