7) Insert screw driver into boot and allow air to enter

boot so that air pressure in boot becomes the same

as atmospheric pressure.

CAUTION

!

• Bend each boot band against forward

rotation.

• Do not squeeze or distort boot when

fastening it with bands. Distorted boot

caused by squeezing air may reduce its

durability.

8) Place differential side boot new big band (3) and new

small band (4) onto boot putting band outer end (1)

against forward rotation (2) as shown in figure.

9) Fasten differential side boot big band.

Differential

Front

General Description

Front Differential Construction

S5JB0A3211001

The differential assembly uses a hypoid bevel pinion and gear.

The differential assembly is decisive in that the drive power is concentrated there. Therefore, use of genuine parts and

specified torque is compulsory. Further, because of sliding tooth meshing with high pressure between bevel pinion and

gear, it is mandatory to lubricate them by hypoid gear oil.
