DIFFERENTIAL OIL
ADJUSTMENT
1. INSPECT AND ADJUST DIFFERENTIAL OIL
a. Stop the vehicle on a level place.
b. Remove the differential filler plug and gasket.
c. Check that the oil surface is within 5 mm (0.20 inch) of the lowest position of the inner surface of the differential filler plug opening.
NOTICE:
- Excessively large or small amounts of oil may cause trouble.
- After replacing oil, drive the vehicle and check the oil level.
HINT: If necessary, fill the rear differential carrier with hypoid gear oil.
Oil grade: Hypoid gear oil API GL-5
Recommended oil viscosity:
Above -18°C (0°F) SAE 90
Below -18°C (0°F) SAE 80W or 80W-90
Capacity: 0.9 ± 0.05 liters (0.95 ± 0.05 US qts, 0.79 ± 0.04 Imp. qts)
d. Check for oil leakage when the oil level is low.
e. Install the differential filler plug and a new gasket.
Torque: 49 Nm (500 kgf-cm, 36 ft. lbs.)
