Differential Gear Oil
DIFFERENTIALS
2. Differential Gear Oil
A: INSPECTION
1) Remove the filler plug, and then check the gear
oil. Replace the gear oil if it is contaminated or de-
teriorated. ential Gear Oil.>
2) Check that the gear oil level is up to the bottom
of the filler plug hole. If the level is low, refill up to
the bottom of filler plug.
B: REPLACEMENT
1) Jack–up the vehicle and support it with rigid
racks.
2) Remove the oil drain plug and filler plug, and
drain the gear oil.
CAUTION:
Be careful not to burn your hands, because
gear oil becomes extremely hot after running.
3) Tighten the oil drain plug.
NOTE:
Use a new metal gasket.
Tightening torque:
29 N·m (3.0 kgf-m, 21.7 ft-lb)
4) Fill the differential carrier with gear oil to the bot-
tom of filler plug.
NOTE:
Carefully refill oil while watching the level. Exces-
sive or insufficient oil must be avoided.
