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. <Ref. to DI-26, REPLACEMENT, Differ-
ential Gear Oil.>
2) Check that the gear oil level is within –5 mm (–0.2 in)
from the bottom of the filler plug hole. If the level is low,
confirm that there is no oil leakage and refill up to the
bottom of filler plug.

NOTE:
On VA1-types at factory settings, the oil level may
be within –14 mm (–0.6 in) from the bottom of the
filler plug. This is at normal level, requiring no oil re-
fill.

B: REPLACEMENT

1) Lift up the vehicle.
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.
