  1. INSPECT DIFFERENTIAL OIL Stop the vehicle on the level place. Remove the differential filler plug and gasket. Check that the oil surface is within 5 mm (0.20 in.) from the lowest position of the inner surface of the differential filler plug opening. NOTE: Excessively large or small amount of oil may cause troubles. After replacing oil, drive the vehicle and check the oil level. HINT: If necessary, fill the rear differential carrier assy 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) Check for oil leakage when the oil level is low. Install the differential filler plug and a new gasket. Torque: 49 N.m (500 kgf.cm, 36 ft.lbf)
