WHEEL ALIGNMENT

WARNING:

• Always perform the following procedure on a flat surface.
• Check that no person is in front of vehicle before pushing it.

1.

Bounce front of vehicle up and down to stabilize the vehicle height (posture).

2.

Push vehicle straight ahead about 5 m (16 ft).

3.

Put matching mark (A) on base line of the tread (rear side) of
both tires at the same height of hub center. These are measur-
ing points.

4.

Measure distance (A) (rear side).

5.

Push vehicle slowly ahead to rotate wheels 180 degrees (1/2
turn).
NOTE:
If the wheels rotates more than 180 degrees (1/2 turn), start this
procedure again from the beginning. Do not push the vehicle
backward.

6.

Measure distance (B) (front side).

• If toe-in exceeds the standard value, adjust toe-in by varying the length of between steering outer socket

and inner socket.

FRONT COIL SPRING AND STRUT

Be sure a spring compressor is securely attached to coil spring. Compress coil spring.

4.

Check coil spring with a spring compressor between spring upper seat and lower seat (strut assembly) is
free. And then remove piston rod lock nut while securing the piston rod tip so that piston rod does not turn.

5.

Remove strut mounting bearing, spring upper seat, and bound bumper as a set.

6.

Remove bound bumper from spring upper seat.

7.

Remove strut mounting bearing (1) from spring upper seat (2),
using a drift (A) (SST: KV10106700).

8.

After removing coil spring with a spring compressor, then gradu-
ally release a spring compressor.

CAUTION:

Loosen while making sure coil spring attachment position
does not move.

9.

Remove the strut attachment (SST: ST35652000) from strut.

ASSEMBLY

1.

Install strut attachment (SST: ST35652000) to strut and secure it in a vise.

CAUTION:

When installing the strut attachment to strut assembly, wrap a shop cloth around strut to protect
from damage.

2.

Install strut mounting bearing (1) to spring upper seat (2), using
a drift (A) (SST: KV10106700).

CAUTION:

Never press to aluminum shield.

3.

Install bound bumper to spring upper seat.

4.

Compress coil spring using a spring compressor (commercial service tool), and install it onto strut assem-
bly.

CAUTION:

• Face tube side of coil spring (1) downward. Align the

lower end (A) to lower seat (strut assembly) (2).

• Be sure a compressor is securely attached to coil spring.

Compress coil spring.

5.

Install strut mounting bearing, spring upper seat, and bound
bumper as a set.

6.

Secure piston rod tip so that piston rod does not turn, then
tighten piston rod lock nut with specified torque.

7.

Gradually release a spring compressor, and remove coil spring.

CAUTION:

Loosen while making sure coil spring attachment position
does not move.

8.

Remove the strut attachment from strut assembly.

9.

Install strut mounting insulator.

Disposal

INFOID:0000000006046092

1.

Set strut assembly horizontally to the ground with the piston rod fully extracted.

2.

Drill 2 – 3 mm (0.08 – 0.12 in) hole at the position (

) from top

as shown in the figure to release gas gradually.

CAUTION:

• Wear eye protection (safety glass).
• Wear gloves.
• Be careful with metal chips or oil blown out by the com-

pressed gas.

NOTE:
• Drill vertically in this direction (

).

• Directly to the outer tube avoiding brackets.
• The gas is clear, colorless, odorless, and harmless.

3.

Position the drilled hole downward and drain oil by moving the piston rod several times.

CAUTION:
