3.

Apply soapy water to bound bumper.

CAUTION:

Never use machine oil.

4.

Insert bound bumper into mounting insulator.

5.

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

CAUTION:

• Be sure a spring compressor is securely attached to coil spring, before compress coil spring.
• Align the lower end of coil spring (1) with “A” of lower

rubber seat (2) as shown in the figure.

• Set coil spring so that its paint marks are aligned with the

positions of 1.25 turns and 2.25 turns from the bottom end
of the coil spring.

6.

Check the location of protrusion (A) of the mounting insulator
and install it with faced outside of the vehicle to the strut.

7.

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.

8.

Gradually release a spring compressor (A) (commercial service
tool), and remove coil spring.

CAUTION:

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

9.

Remove the strut attachment (A) [SST: ST35652000 (

—

)]

from strut assembly.

FRONT COIL SPRING AND STRUT

Check the following items, and replace the parts if necessary.

Strut

• Strut for deformation, cracks or damage
• Piston rod for damage, uneven wear or distortion
• Oil leakage

Strut Mounting Insulator and bound bumper

Check strut mounting insulator and bound bumper for cracks, wear or damage.

Coil Spring

Check coil spring for cracks, wear or damage.

INSPECTION AFTER INSTALLATION

1.

Check wheel sensor harness for proper connector. Refer to 

BRC-119, "FRONT WHEEL SENSOR :

Exploded View"

.

2.

Check wheel alignment. Refer to 

FSU-7, "Inspection"

.

3.

Adjust neutral position of steering angle sensor. Refer to 

BRC-49, "Work Procedure"

 (with VDC).

Disposal

INFOID:0000000009650671

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 glasses).
• Wear gloves.
• Be careful with metal chips or oil blown out by the com-

pressed gas.

NOTE:
• Drill vertically in this direction show by arrow.
• 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.
