Removal & Installation Procedure1. Disconnect (-) cable from battery.
2. Lift on vehicle and make sure on safety. NoticeBe careful for catalytic converter due to high temperature after driving or engine running.
3. Prepare a vessel to drain transfer case and manual transmission oil.
4. Release drain plug and drain transfer case and manual transmission oil. If planar damper is installed, unscrew 4 bolts and remove
the planar damper. NoticeOil drain should be along with whole transfer case
disassembly and assembly.
5. Disconnect transmission extension wiring connector back
side transfer case. Notice
When disconnect connector, make sure on direction of locking tab towards inside.
6. Disconnect shift motor/clutch coil connect (Black 7 pin) connector upper backside.
7. Disconnect front and rear speed sensor connector (white 7 pin).
8. Disconnect speedometer sensor connector right upper side.
9. Disconnect breather tube front upper side transfer case (upper connecting point of transfer case and front propeller).
10. Prepare hydraulic jack and support transfer case assembly.

MAINTENANCE AND REPAIR ON-VEHICLE SERVICE INSPECTION Steering Wheel Freeplay Inspection Procedure
1. Start the engine and set the wheels in straight ahead position.
2. Slightly move the steering wheel to the left and right andmeasure steering wheel free play when the front wheel is
start to move. Notice
If exceeds specification, the steering column shaft
connections and steering linkage .clearance. Replace orrepair if necessary.
Steering Angle Inspection Procedure
1. Place the front wheel on a measuring tool.
2. Rotate steering wheel all the way right and left and measure steering angle Notice If out of standard, check or adjust toe-in.

Steering Effort Inspection Procedure
1 Place a vehicle on the paved flat ground with front wheels in a straight ahead position.
2 Start the engine and run it at 1,000rpm.
3 Using a scale, measure the steering effort in both directions.
NoticeThe difference in steering effort of left and right should be within 0.6 kg.
Standard Max. 3.0kg
StandardMax. 30mm

OIL PUMP PRESSURE CHECK Oil Pump Pressure Check
1. Disconnect the pressure hose from the oil pump connect apressure gauge between the oil pump and pressure hose
2. Bleed the system . Start the engine and turn the steering wheel form lock several times until oil temperature is up to
50°C
3. Run the engine at 1,000 rpm.
4. Close the pressure gauge valve and check oil pressure.
NoticeDo not keep the valve closed for more than 10 seconds.
5. Remove the pressure gauge and connect the pressure hose.
6. Do bleeding procedure. BLEEDING OF POWER STEERING SYSTEM Bleeding of Power Steering System
1. Disconnect the fuel line. Using a starter motor, crank the engine and turn the steering wheel from lock to lock 5 or 6 times. Notice Do bleeding with engine cranking. If bleed with idling, there can be a air contact with oil.
2. Connect the fuel feed line and start the engine at idle speed.
3. Turn the steering wheel from lock to lock until there is no more air in oil reservoir.
4. Connect the oil level is within specification.
5. By turning the steering wheel left to right, check the oil level change. Notice
If oil is not changes more than 5mm, do bleeding again.
If oil level rises suddenly when stopped engine, again.

Water Sensor
Water sensor is a thermistor that detects engine coolant temperature to operate the blower speed to LO when water temperature is less than 50.
1. Check that there are water sensor fault code (15,16) by
using self-diagnosis function.
3. Check that measured resistance value among water sensor terminals is as shown in the right side graph. Notice Measure resistance value by soaking the sensor in the ice water and check changes in resistance values after soaking
it in the very hot water.
4. If resistance value is out of specification, replace the water sensor.
5. Install the sensor and turn the ignition switch to ON position and check that voltage between No. 7a terminal of the water
sensor and body (-) is 5V.
6. Check current between the No. 7a and 7b connector terminals of the water sensor and the No. 3 and 5 connector terminals of the airconditioner control unit and repair the wire if defective.
2. Disconnect water sensor 2-pin connector that installed on
the heater unit of inner instrument panel and remove the
water sensor.
