(d) Using Chassis Dynamometer:
Observe the following instructions and then measure with
the rear wheels.
(1) Remove the front propeller shaft.
(2) Put the center differential in LOCK position.
(3) If the vehicle is equipped with Vehicle Skid Control
(VSC) & Traction Control (TRAC) system, prohibit
the system from the activation (See step 2.).
(4) Ensure that the vehicle is securely fixed.
HINT:
Sudden shifting, braking, acceleration or deceleration is
not allowed.
Do not forget to change the Vehicle Skid Control (VSC) &
Traction Control (TRAC) system to operational condition
after the test. Check that the VSC warning indicator light
goes off when restarting the engine.
(e) On-V ehicle Wheel Balancing:
When doing on-vehicle wheel balancing on a full-time
4WD vehicle, to prevent each wheel from being rotated at
different speed in different directions (which could dam-
age the center differential), always be sure to observe the
following precautions.
(1) All of 4 wheels should be jacked up, being apart
from the ground completely.
(2) Put the center differential in LOCK position.
(3) If the vehicle is equipped with Vehicle Skid Control
(VSC) & Traction Control (TRAC) system, prohibit
the system from the activation (See step 2.).
(4) The parking brake lever should be fully released.
(5) None of the brakes should be applied.
(6) The wheels should be driven on the wheel balancer
with the engine running.
(7) Carry out the wheel balancing with the transmission
position in D position.
HINT:
When doing this balancing, pay attention to the other
wheels rotating at the same time.
Sudden acceleration, deceleration or braking is not al-
lowed.
Do not forget to change the Vehicle Skid Control (VSC) &
Traction Control (TRAC) system to operational condition
after the test. Check that the VSC warning indicator light
goes off when restarting the engine.

NOIf this towing method is used, either from the front or rear:
Never tow the vehicle using a method where the lifted-up wheel
cannot rotate.
Do not use the sling type towing method, either from the front or rear,
as this method causes damage to the body. (a) There is a danger of the drive train heating up and causing break-
down, or of the wheels flying off the dolly.
(b) In addition, if the vehicle is equipped with the Vehicle Skid Control
(VSC) & Traction Control (TRAC) system, the system will apply the
rotating wheels brake unless the engine isn't shut off.

5. WHEN TOWING FULL-TIME 4WD VEHICLES
Use one of the methods shown below to tow the vehicle.
If the vehicle has trouble in the chassis and drive train, use method 1 (flat bed truck).
NOTICE:
Do not use any towing method other than those shown above.
For example, the towing methods shown below are dangerous or damage the vehicle, so do not use
them.

(k) Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the prop-
er locations (See page IN-8).
Cancel the parking brake on the level place and
shift the transmission in N position.
When jacking up the front wheels of the vehicle at
first place stoppers behind the rear wheels.
When jacking up the rear wheels of the vehicle at
first place stoppers before the front wheels.
When either the front or rear wheels only should be
jacked up, set rigid racks and place stoppers in front
and behind the other wheels on the ground.
After the vehicle is jacked up, be sure to support it
on rigid racks. It is extremely dangerous to do any
work on a vehicle raised on a jack alone, even for
a small job that can be finished quickly.
(l) Observe the following precautions to avoid damage to the
following parts:
(1) Do not open the cover or case of the ECU unless
absolutely necessary. (If the IC terminals are
touched, the IC may be destroyed by static electric-
ity.)
(2) To disconnect vacuum hoses, pull off the end, not
the middle of the hose.
(3) To pull apart electrical connectors, pull on the con-
nector itself, not the wires.
(4) Be careful not to drop electrical components, such
as sensors or relays. If they are dropped on a hard
floor, they should be replaced and not reused.
(5) When steam cleaning an engine, protect the elec-
tronic components, air filter and emission-related
components from water.
(6) Never use an impact wrench to remove or install
temperature switches or temperature sensors.
(7) When checking continuity at the wire connector, in-
sert the tester probe carefully to prevent terminals
from bending.
(8) When using a vacuum gauge, never force the hose
onto a connector that is too large. Use a step-down
adapter for adjustment. Once the hose has been
stretched, it may leak air.

INSPECTION
1. INSPECT BRAKE LINE PIPES AND HOSES
HINT:
Check in a well lighted area. Check the entire circumference
and length of the brake hoses using a mirror as required. Turn
the front wheels fully right or left before checking the front brake.
(a) Check the all brake lines and hoses for damage.
(b) Check the all brake lines and hoses for wear.
(c) Check the all brake lines and hoses for deformation.
(d) Check the all brake lines and hoses for cracks.
(e) Check the all brake lines and hoses for corrosion.
(f) Check the all brake lines and hoses for leaks.
(g) Check the all brake lines and hoses for bends.
(h) Check the all brake lines and hoses for twists.
(i) Check all clamps for tightness and connections for leak-
age.
(j) Check that the hoses and lines are clear of sharp edges,
moving parts and the exhaust system.
(k) Check that the lines installed in grommets pass through
the center of the grommets.
2. INSPECT FRONT AND REAR BRAKE PADS AND
DISCS
(FRONT PADS: See page BR-16)
(REAR PADS: See page BR-25)
(FRONT DISCS: See page BR-21)
(REAR DISCS: See page BR-30)
3. INSPECT PARKING BRAKE LININGS AND DRUMS
(See page BR-36)
