Check with the manufacturer of your specific alignment machine for their recommended Service/Cali-
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to FSU-20, "Wheel
Alignment (Unladen*1 )*6" .
1. When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.

The alignment specifications programmed into your alignment machine that operate these indicators
may not be correct.

This may result in an ERROR.
2. Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-
pensate” the sensors (alignment targets or head units). Do NOT use this “Rolling Compensation”
method.

Use the “Jacking Compensation” method. After installing the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.

See Instructions in the alignment machine you are using for more information.
CAMBER AND CASTER
1. Measure camber and caster of both the right and left wheels
with a suitable alignment gauge and adjust as necessary to
specification.
NOTE:
Some vehicles may be equipped with straight (non-adjustable)
lower link bolts and washers. In order to adjust camber and
caster on these vehicles, first replace the lower link bolts and
washers with adjustable (cam) bolts and washers.
2. If outside of the specified value, adjust camber and caster using
the cam bolts (1) in the front lower link (2).
CAUTION:
After adjusting the camber then check the toe-in.
NOTE:
Camber changes about 3' (0.05°) minutes with each graduation
of one cam bolt. Refer to table below for examples of lower link
cam bolt effect on camber and caster.
3. Tighten the adjusting bolt nuts to specification. Refer to FSU-5, "
Components" .
TOE-IN
WA RN ING:

Always perform the following procedure on a flat surface.

Make sure that no person is in front of the vehicle before pushing it.Camber and
Caster: Refer to FSU-20, "

1. Bounce the front of vehicle up and down to stabilize the vehicle height (posture).
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both front tires
at the same height as hub center as shown. These marks are
measuring points.
4. Measure the distance “A” on the rear side of the front tires as
shown.
5. Push the vehicle slowly ahead to rotate the wheels 180°
degrees (1/2 a turn).
CAUTION:
If the wheels have rotated more than 180° degrees (1/2
turn), start this procedure again from the beginning. Never
push the vehicle backward.
6. Measure the distance “B” on the front side of the front tires at the
same marks as shown. Total toe-in is calculated as “A” – “B”.
7. Adjust the toe-in by varying the length of the steering outer
socket.
a. Loosen the outer tie-rod lock nuts.
b. Adjust the toe-in by screwing the outer tie-rods in or out.
c. Tighten the outer tie-rod lock nuts to specification.
FRONT WHEEL TURNING ANGLE
NOTE:
Check front wheel turning angle after the toe-in inspection.
1. Place front wheels on turning radius gauges in straight ahead
position and rear wheels on stands so that vehicle can be level.
Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
2. Start engine and run at idle, turn steering wheel all the way right
and left, measure the turning angle.

Any turning angles are not adjustable. If any of steering
angles are out of the specification, check if the following parts
are worn or damaged.

PRECAUTIONS
Revision: October 20052005 QX56
General PrecautionsEAS001F7

Do not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any
inflammable or poisonous materials, such as gasoline, refriger-
ant gas, etc. When working in a pit or other enclosed area, be
sure to properly ventilate the area before working with hazard-
ous materials.
Do not smoke while working on the vehicle.

Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before working
on the vehicle.
These operations should be done on a level surface.

When removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.

Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.

If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.

To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.

Dispose of drained oil or the solvent used for cleaning parts in
an appropriate manner.

Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel
spray and possibly a fire.

Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.

Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.

Replace inner and outer races of tapered roller bearings and needle bearings as a set.

Arrange the disassembled parts in accordance with their assembled locations and sequence.

Do not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.

After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.

Use only the fluids and lubricants specified in this manual.

damaging the vehicle body, use proper towing equipment when
towing.
Vehicle Recovery (Freeing a stuck vehicle)EAS001FZ

Tow chains or cables must be attached only to the main structural members of the vehicle or the
towing hooks (if so equipped). Otherwise, the vehicle body will be damaged.

Use the towing hook (if so equipped) only to free a vehicle stuck in sand, snow, mud, etc. Never
tow the vehicle for a long distance using only the towing hook.

The towing hook is under tremendous force when used to free a stuck vehicle. Never pull the hook
at an angle.

Always pull the cable straight out from the front or rear of the vehicle.

Pulling devices should be routed so they do not touch any part of the suspension, steering, brake,
or cooling systems.

Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or
recovery.
WA RN ING:

Stand clear of a stuck vehicle.

Do not spin your tires at high speed. This could cause them to explode and result in serious injury.
Parts of your vehicle could also overheat and be damaged.
