(2) If the hydraulic unit function has been stopped by
fail-safe, the hydraulic unit cannot be forcibly driven.
6. Check that the generated oil pressure of the hydraulic
unit satisfies the standard value.
Standard value: 1.0 – 1.6 MPa
Caution
While the oil pressure is checked, add fluid as
necessary to ensure that it is left in the oil reservoir
during the entire procedure.
7. If the measured value exceeds the standard value, replace
the hydraulic unit.
8. Connect the hydraulic unit and transfer connector
assembly, and tighten the flare nut at the specified torque.
Tightening torque: 34±5 N·m (when screw is dry)
26±4 N·m (when screw is applied with oil)
9. Supply the specified fluid up to the MAX level of the
oil reservoir, and bleed the oil pressure pipes.
Specified fluid: DIA QUEEN ATF SP III

MEASUREMENT (VEHICLES WITHOUT AYC)>
1. Lift the vehicle, and release the parking brake.
2. Disconnect the 4WD-ECU connector, and measure at
the connector of the harness.
Caution
Insert the probe from the harness of the connector.
Inserting in the terminal side may cause contact fault.
3. Rotate the measured wheel by about 1/2 to 1
rotations/second, and check the output voltage between
the following terminals using a circuit tester (AC mV range)
or oscilloscope.

WHEEL BEARING AXIAL PLAY CHECK
1. Remove the disc brake caliper and suspend it with a
wire.
2. Remove the brake disc from the front hub.
3. Attach a dial gauge as shown in the illustration, and then
measure the axial play while moving the hub in the axial
direction.
Limit: 0.06 mm
4. If axial play exceeds the limit, replace the front hub
assembly.
HUB BOLT REPLACEMENT
1. Remove the caliper assembly and secure it with wire
so that it does not fall.
2. Remove the brake disc.
3. Use the special tools to remove the hub bolts.
4. Install the plain washer to the new hub bolt, and install
the bolt with a nut.

AA"CALIPER ASSEMBLY REMOVAL
Secure the removed caliper assembly with wire, etc.
Caution
If the vehicle is equipped with the Brembo disc brake,
during maintenance, take care not to contact the parts
or tools to the caliper because the paint of caliper will
be scratched. And if there is brake fluid on the caliper,
wipe out quickly.
AB"CASTLE NUT REMOVAL
Caution
Do not apply the vehicle weight to the wheel bearing
while loosening the castle nut. Otherwise wheel bearing
will be damaged.
AC"TIE ROD END DISCONNECTION
Caution
1. Loosen the nut only; do not remove it from the ball
joint. Otherwise ball joint thread will be damaged.
2. The special tool should be suspended by a cord to
prevent it from coming off.
AD"DRIVE SHAFT REMOVAL
1. Use the special tools to push out the drive shaft from
the hub.
2. Withdraw the drive shaft from the hub by pulling the bottom
of the brake disc towards you, and then remove the hub
retaining bolts.

contact the parts or tools to the caliper because the paint of caliper will be scratched. And
if there is brake fluid on the caliper, wipe out quickly.
2. For vehicles with ABS or ACD, do not strike the rotor for wheel speed sensor installed to
the B.J. outer race of drive shaft against other parts when removing or installing the drive
shaft. Otherwise the rotor for wheel speed sensor will be damaged.

Caution
1. Loosen the nut only; do not remove it from the ball
joint. Otherwise ball joint thread will be damaged.
2. The special tool should be suspended by a cord to
prevent it from coming off.
AB"DRIVE SHAFT REMOVAL
1. Use the special tools to push out the drive shaft from
the hub.
2. Withdraw the drive shaft from the hub by pulling the bottom
of the brake disc towards you, and then remove the hub
retaining bolts.
3. Remove the drive shaft from the transmission by the
following procedure.
Insert a pry bar between the transmission case and the
drive shaft, and then pry the drive shaft from the
transmission.
Caution
(1) Do not pull on the drive shaft; doing so will damage
the T.J.; be sure to use the pry bar.
(2) When pulling the drive shaft out from the
transmission, be careful that the spline part of
the drive shaft does not damage the oil seal.
(3) Do not apply the vehicle weight to the wheel
bearing while loosening the drive shaft nut.
Otherwise wheel bearing will be damaged. If,
however, the vehicle weight must be applied to
the bearing (because of moving the vehicle),
temporarily secure the wheel bearing by using
the special tool.
