ON±VEHICLE WHEEL BALANCING
NOTICE:
1. When doing on±the±car wheel balancing on a fulltime
4WD vehicle, to prevent the wheels from rotating at
different speeds or in different directions from each
other (which could lead to damage to the center differ-
ential or transaxle gears), always be sure to observe
the following precautions:
(1) Aft four wheels should be jacked up, clearing the
ground completely.
(2) The wheels should be driven with both the engine
and the wheel balancer.
(3) The mechanical lock±type center differential
should be in the LOCK position.
(4) The parking brake lever should be fully released.
(5) None of the brakes should be allowed to drag.
2. Avoid sudden acceleration, deceleration and braking.
3. Carry out the wheel balancing with the transmission in
3rd or 4th gear.
1. PUT CENTER DIFFERENTIAL IN ºLOCKº POSITION
(1) Set the center differential control switch to ON and
check that the differential lock indicator fight goes on.
HINT: If the indicator light does not go on when the
center differential control switch is turned on, move
the vehicle backward or forward slightly.
(2) Put the transmission in neutral.
(3) Jack up one wheel and check that the wheel cannot be
rotated by hand.
2. JACK UP VEHICLE SO THAT ALL FOUR WHEELS CAN
ROTATE
The wheels will be rotating fast, so make sure the vehicle is
firmly supported on stands.
3. RELEASE PARKING BRAKE FULLY

9. SET CENTER DIFFERENTIAL CONTROL SWITCH TO
OFF
HINT: If the indicator light does not go off when the center
differential control switch is turned off, move the vehicle
backward or forward slightly and check that the indicator light
goes off.8. ROTATE WHEELS USING BOTH ENGINE'S DRIVING
FORCE AND DRIVING FORCE OF WHEEL BALANCER
AND CHECK WHEEL BALANCE
HINT: When doing this be careful of the other wheels, which
will rotate at the same time. 6. START ENGINE
7. PUT TRANSMISSION IN 3RD OR 4TH GEAR AND
ENGAGE CLUTCH SLOWLY, THEN GRADUALLY
INCREASE SPEED TO TEST SPEED 5. PLACE WHEEL TO BE BALANCED ON WHEEL
BALANCER
Follow the procedure specified by the wheel balancer
manufacturer. 4. MAKE SURE THAT BRAKES ARE NOT DRAGGING ON
ANY OF FOUR WHEELS

2. AUTOMATIC TRANSAXLE
MODELS: (Hydraulic Multiplate
Clutch Control Type Center
Differential)
BEFORE BEGINNING TEST
During tests with a brake tester or chassis dynamometer,
such as braking force tests or speedometer tests, if only the
front or the rear wheels are to be rotated, it is necessary to
first set the center differential control switch to OFF (Hydrau-
lic multiplate clutch control is released), then set the Mode
Select Lever on the automatic transaxle to the FREE (Nor-
mal) Mode or to the LOCK
Mode depending on the type of test being performed.
1. Release Hydraulic Multiplate Clutch
Control of Center Differential
1. SET CENTER DIFFERENTIAL CONTROL SWITCH TO
OFF AND CHECK THAT INDICATOR LIGHT GOES OFF
2. CHECK THAT OPERATION OF HYDRAULIC
MULTIPLATE CLUTCH CONTROL IS IN ºOFFº
CONDITION
(1) Jack up the vehicle so that all four wheels can rotate.
(2) Apply the parking brake.
(3) Start the engine and run it at idle speed.
When the engine speed is high, warm±up the en-
gine, then run it at idle speed.

2. REMOVE MODE SELECT LEVER LOCK BOLT
3. MOVE MODE SELECT LEVER TO DESIRED MODE
POSITION
While rotating one front wheel by hand, shift the select lever
towards the LOCK mode or FREE mode.
HINT: Do not use excessive force when moving the mode
select lever.
4. AFTER MAKING SHIFT, LOCK MODE SELECT LEVER
SECURELY WITH BOLT
HINT: Be sure to tighten the lock bolt securely each time after
moving the mode select lever.(4) Depress the brake pedal, shift into L range and gradu-
ally release the brake pedal.
(5) Check that the front wheels begin to rotate and that the
rear wheels do not rotate.
2. Moving Mode Select Lever
1. JACK UP VEHICLE(6) Stop the engine and put the transmission in N range.

CAUTIONS WHEN MODE SELECT LEVER IS IN ºFREEº
OR ºLOCKº MODE
FREE MODE
(1) Do not drive off suddenly or apply the accelerator or
brakes suddenly. Always start slowly and decelerate
gradually.
(2) If either the front or the rear wheels are placed on the
tester rollers in the FREE mode, be careful not to exceed
the following limits:
Maximum speed:
Speed indicated on speedometer
19 mph(30 km/h) or
Wheel speed (Tester speed)
38 mph160 km/h)
Maximum test time: 60 sec.
Note that the actual wheel speed (tester speedy is twice the
speed indicated by the speedometer due
to center differential operation.
LOCK MODE
(1) Do not drive off suddenly or apply the accelerator or
brakes suddenly. Always start slowly and decelerate
gradually.
(2) Be sure to conduct the test with the rear propeller
shaft removed.6. AFTER FINISHING TEST, RETURN MODE SELECT
LEVER TO ºFREE (NORMAL)º MODE POSITION AND
LOCK SELECT LEVER SECURELY WITH BOLT
7. SET CENTER DIFFERENTIAL CONTROL SWITCH TO
AUTO 5. CONFIRM MODE
FREE (Normal) Mode:
A lifted wheel can be rotated even if only one wheel is lifted
up, as long as transmission is in N range.
LOCK Mode:
A lifted wheel cannot be rotated if only one wheel is
lifted up, even if transmission is in N range.
