The differential assembly is decisive in that the drive
power is concentrated there. Therefore, use of genu-
ine parts and specified torque is compulsory. Further,
because of sliding tooth meshing with high pressure
between bevel pinion and gear, it is mandatory to lu-
bricate them by hypoid gear oil.

GENERAL DESCRIPTION
The differential assembly using a hypoid bevel pinion
and gear is installed to the rear axle. It is set in the con-
ventional type axle housing.
The reduction ratio and differential case vary depend-
ing on transmission or engine type.

MAINTENANCE SERVICE
NOTE:

When having driven through water, check immediately if wa-
ter has entered (if so, oil is cloudy). Water mixed oil must be
changed at once.

Whenever vehicle is hoisted for any other service work than
oil change, also be sure to check for oil leakage and status
of breather hoses.
CHANGING OIL
NOTE:

Hypoid gear oil must be used for differential.

It is highly recommended to use SAE 80W-90 viscosity.
1) Before oil change or inspection, be sure to stop engine and lift
up vehicle horizontally.
2) Check oil level and existence of leakage. If leakage is found, cor-
rect its cause.
3) Drain old oil and pour proper amount of gear oil as specified
(roughly up to level hole).
4) Torque drain and level / filler plugs to specification.
