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.

Removal and InstallationEES002KO
REMOVAL
1. Remove the wheel.
2. Support the lower link using a suitable jack.
3. Remove connecting rod upper joints from stabilizer bar. Refer toFSU-6, "
Components".
lSwing stabilizer bar down, repositioning it out of the way to access shock absorber lower mount.
4. Remove the shock absorber lower bolt and nut.
5. Remove the three shock absorber upper mounting nuts.
6. Remove the coil spring and shock absorber assembly.
lTurn steering knuckle out to gain enough clearance for
removal.
INSTALLATION
Installation is in the reverse order of removal.
lThe step in the strut assembly lower seat faces outside of vehicle.
lTighten all nuts and bolts to specification. Refer toFSU-6, "Components".
lWhen installing wheel and tire, refer toWT-5, "Rotation".
Disassembly and AssemblyEES002KP
DISASSEMBLY
1. Install strut attachment to strut and fix it in a vise.
CAUTION:
When installing strut attachment, wrap a shop cloth around
strut to protect it from damage.
2. Slightly loosen piston rod lock nut.
WARNING:
Do not remove piston rod lock nut completely. If it is
removed completely, coil spring jumps out and may cause
serious damage or injury.
3. Compress the spring using commercial service tool until the
shock absorber mounting insulator can be turned by hand.
WARNING:
Make sure that the pawls of the two spring compressors are firmly hooked on the spring. The
spring compressors must be tightened alternately and evenly so as not to tilt the spring.
4. Remove the piston rod lock nut.
lDiscard the piston rod lock nut, use a new nut for assembly.
5. Remove the components from the shock absorber.
lKeep the spring compressed in the commercial service tool if
reusing it for assembly.
