Disassembly and Assembly

INFOID:0000000010297072

DISASSEMBLY

CAUTION:

Never damage strut assembly piston rod when removing components from strut assembly.
1.

Install strut attachment (A) (SST: ST35652000) to strut assem-
bly 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.

FRONT COIL SPRING AND STRUT

2.

Using a spring compressor (A) (commercial service tool), com-
press coil spring between strut mounting bearing and lower rub-
ber seat (on strut assembly) until coil spring with a spring
compressor is free.

CAUTION:

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

3.

Make sure coil spring with a spring compressor between strut
mounting bearing and lower rubber 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.

4.

Remove strut mounting insulator and strut mounting bearing,
and bound bumper from strut.

5.

After remove coil spring with a spring compressor, and then gradually release a spring compressor.

CAUTION:

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

6.

Remove lower rubber seat from strut.

7.

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 lower rubber seat.

3.

Install bound bumper.

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 rubber seat (2).

• Be sure a spring compress is securely attached to coil

spring. Compress coil spring.

5.

Install strut mounting bearing and strut mounting insulator to strut.

6.

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

CAUTION:

Never reuse piston rod lock nut.

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.

INSPECTION AFTER INSTALLATION

1.

Check wheel alignment. Refer to 

FSU-7, "Wheel Alignment Inspection"

.

2.

Adjust neutral position of steering angle sensor. Refer to 

BRC-64, "Work Procedure"

.

Disposal

INFOID:0000000010425116

1.

Set front coil spring and strut 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 glasses).
• 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:

Dispose of drained oil according to the law and local regulations.
