Torque:

370 N*m{3773 kgf*cm, 273 ft.*lbf}or less

Using a torque wrench, measure the preload.

Standard Preload (Starting Torque):

Item	Specified Condition
New bearing	1.0 to 1.5 N*m (11 to 15 kgf*cm, 9 to 13 in.*lbf)
Reused bearing	0.5 to 0.7 N*m (6 to 7 kgf*cm, 5 to 6 in.*lbf)

1. If the result is not as specified, adjust the preload (Toyota Fortuner RM0000010MO01UX_01_0012.html).
   

Using a torque wrench, measure the preload with the teeth of the drive pinion and ring gear in contact.

Standard total preload (starting torque):

0.3 to 0.8 N*m (4 to 8 kgf*cm, 3 to 7 in.*lbf) + drive pinion preload

Using a chisel and hammer, stake the nut.

Add differential oil so that the oil level is within 5 mm (0 to 0.196 in.) from the bottom lip of the differential filler plug hole.

NOTICE:

1. After changing the oil, drive the vehicle, and then check the oil level again.
   
2. Too much or too little oil will lead to differential problems.
   

Recommended viscosity:

Temperature	Viscosity
Above -18°C (0°F)	SAE 90
Below -18°C (0°F)	SAE 80W-90 or SAE 80W

Standard oil grade:

Item	Specified Condition
Front differential (4WD)	Hypoid gear oil API GL-4 or GL-5
Rear differential	Hypoid gear oil API GL-5

Standard front differential oil capacity:

1.40 to 1.50 liters (1.48 to 1.59 US qts., 1.23 to 1.31 Imp. qts.)
