REPLACEMENT

1) Lift up the vehicle. 
2) Remove the differential gear oil drain plug using TORX(R) bit T70, and drain the differential gear oil completely.

CAUTION:
^

Immediately after driving the vehicle or after idling for a long time, the differential gear oil will be hot. Be careful not to receive burns. 

^

Be careful not to spill differential gear oil on the exhaust pipe to prevent it from emitting smoke or causing a fire. If differential gear oil is
spilled on the exhaust pipe, wipe it off completely.

3) Replace the gasket with a new part and tighten the differential gear oil drain plug using the TORX(R) bit T70.

Tightening torque:

Aluminum gasket (silver)

44 N-m (4.5 kgf-m, 32.5 ft-lb)

Copper gasket (brown)

70 N-m (7.1 kgf-m, 51.6 ft-lb)

Metal gasket (black)

70 N-m (7.1 kgf-m, 51.6 ft-lb)

4) Lower the vehicle. 
5) Fill the differential with differential gear oil from the level gauge hole.

Gear oil capacity:

1.1 - 1.3 l (1.2 - 1.4 US qt, 1.0 - 1.1 Imp qt) 

6) Check the level of differential gear oil. See: Fluid - A/T/Service and Repair/Differential Fluid Level Check
