Torque:

370 N*m{3,770 kgf*cm, 273 ft.*lbf}or less

Using a torque wrench, measure the preload.

Standard preload (at start of torque):

Item	Specified Condition
New bearing	0.98 to 1.57 N*m (10 to 16 kgf*cm, 8.7 to 13.9 in.*lbf)
Reused bearing	0.49 to 0.78 N*m (5 to 8 kgf*cm, 4.3 to 6.9 in.*lbf)

1. If the result is not as specified, adjust the preload (Toyota Fortuner RM0000010MN002X_01_0003.html).
   

Using a chisel and hammer, stake the nut.

Install the propeller shaft (Toyota Fortuner RM000000ZYG008X.html).

Refill differential oil (Toyota Fortuner RM0000010MD004X.html).

Stop the vehicle on a level surface.

Remove the differential filler plug and gasket.

Check that the oil level is between 0 to 5 mm (0 to 0.20 in.) from the bottom lip of the differential filler plug hole.

NOTICE:

1. After changing the oil seal, drive the vehicle and then check the oil level again.
   

1. Too much or too little oil will lead to differential problems.
   

HINT:

If necessary, fill the differential carrier assembly with hypoid gear oil.

Recommended viscosity:

Temperature	Viscosity
Above -18°C (0°F)	SAE 90
Below -18°C (0°F)	SAE 85W - 90

Standard oil grade:

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.)

Standard rear differential oil capacity:

3.30 to 3.40 liters (3.49 to 3.59 US qts., 2.90 to 2.99 Imp. qts.)

Check for oil leakage when the oil level is low.

Install the differential filler plug with a new gasket.

Torque:

39 N*m{400 kgf*cm, 29 ft.*lbf}for front differential

49 N*m{500 kgf*cm, 36 ft.*lbf}for rear differential
