lWhen installing the rubber bushings, the final tightening must be done under unladen condition and with
the tires on level ground. Oil will shorten the life of the rubber bushings, so wipe off any spilled oil immedi-
ately.
lUnladen condition means the fuel tank, engine coolant and lubricants are at the full specification. The
spare tire, jack, hand tools, and mats are in their designated positions.
lAfter installing suspension components, check the wheel alignment.
lLock nuts are not reusable. Always use new lock nuts for installation. New lock nuts are pre-oiled, do not
apply any additional lubrication.

Front Suspension PartsEES002KM
Check front suspension parts for excessive play, cracks, wear and
other damage.
lShake each front wheel to check for excessive play.
If looseness is noted, inspect wheel bearing end play, then
check ball joint end play. Refer toFSU-15, "
Inspection".
lMake sure that the cotter pin is inserted in drive shaft end (4WD
models only).
lRetighten all nuts and bolts to the specified torque.
lCheck shock absorber for oil leakage and other damage.
lCheck suspension ball joint for grease leakage and ball joint
dust cover for cracks and other damage.
Front Wheel AlignmentEES002KN
PRELIMINARY INSPECTION
WARNING:
Always adjust the alignment with the vehicle on a flat surface.
NOTE:
If alignment is out of specification, inspect and replace any damaged or worn rear suspension parts before
making any adjustments.
1. Check and adjust the wheel alignment with the vehicle under unladen conditions. “Unladen conditions”
means that the fuel, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in
their designated positions.
2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for run out and damage. Refer toWT-3, "
Inspection".
4. Check the wheel bearing axial end play. Refer toFA X - 5 , "
WHEEL BEARING INSPECTION".
5. Check the shock absorbers for leaks or damage.
6. Check each mounting point of the suspension components for any excessive looseness or damage.
7. Check each link, arm, and the rear suspension member for any damage.
8. Check the vehicle height. Refer toFSU-21, "
Wheelarch Height (Unladen*1)". Suspension component torques : Refer toFSU-6,
"Components".SMA525A

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 tie-
rods.
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.
lAny turning angles are not adjustable. If any of steering
angles are out of the specification, check if the following parts
are worn or damaged.
–Steering gear
–Steering column
–Front suspension components
If found that they are worn or damaged, replace them with new ones.

Aiming Adjustment
EKS00P7Y
For details, refer to the regulations in your state.
Before performing aiming adjustment, check the following.
1. Ensure all tires are inflated to correct pressure.
2. Place vehicle and screen on level surface.
3. Ensure there is no load in vehicle other than the driver (or equivalent weight placed in driver's position).
Coolant and engine oil filled to correct level, and fuel tank full.
4. Confirm spare tire, jack and tools are properly stowed.
LOW BEAM AND HIGH BEAM
NOTE:
Aim each headlamp individually and ensure other headlamp beam pattern is blocked from screen.
1. Turn headlamp low beam ON.
2. Use adjusting screws to perform aiming adjustment.
lFirst tighten the adjusting screw all the way and then make adjustment by loosening the screw.
If the vehicle front body has been repaired and/or the headlamp assembly has been replaced, check
aiming. Use the aiming chart shown in the figure.

Aiming AdjustmentEKS00P4D
The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.
lKeep all tires inflated to correct pressure.
lPlace vehicle on level surface.
lSee that vehicle is unloaded (except for full levels of coolant, engine oil and fuel, and spare tire, jack, and
tools). Have the driver or equivalent weight placed in driver's seat.
Adjust aiming in the vertical direction by turning the adjustment
screw.
NOTE:
Use a Phillips screwdriver to adjust. Turn screw clockwise to raise
pattern and counterclockwise to lower pattern.
1. Set the distance between the screen and the center of the fog
lamp lens as shown.
2. Turn front fog lamps ON.
3. Remove front portion of fender protector(s) for adjusting screw
access. Refer toEI-22, "
Removal and Installation of Front
Fender Protector".
4. Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone is 100 mm (4 in) below the height of
the fog lamp centers as shown.
lWhen performing adjustment, if necessary, cover the headlamps
and opposite fog lamp.
