Be sure to remove lubricants if lubricant has been used to separate the connection of strut assembly
and steering knuckle.
Install the steering knuckle to strut assembly as follows.

1.

Set suitable jack under steering knuckle. 

2.

Align the gap 

 of steering knuckle to the projection part 

 of

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.

2.

Using a spring compressor (A) (commercial service tool), com-
press coil spring between spring upper seat and lower seat
(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.

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.

4.

Remove mounting insulator, mounting bearing, upper rubber seat and bound bumper from strut.

5.

After removing coil spring with a spring compressor (commercial service tool), then gradually release a
spring compressor.

CAUTION:

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

6.

Remove lower rubber seat.

7.

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

8.

Perform inspection after disassembly. Refer to 

FSU-15, "Inspection"

FRONT COIL SPRING AND STRUT

2.

Install lower rubber seat with its protrusion 

 on the lower area

aligned with the hole 

 on the strut.

3.

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 

 with lower rubber

seat 

 as shown in the figure.

• Set coil spring so that its paint marks 

 is aligned with

the position of 1.75 turns from the bottom end of the coil
spring.

4.

Apply soapy water to bound bumper.

CAUTION:

Never use machine oil.

5.

Set bound bumper to piston rod of strut.

6.

Install mounting bearing, mounting insulator and upper rubber seat on to spring.

CAUTION:

Never apply oils, such as grease, when installing the mounting bearing and mounting insulator.

7.

Set the mounting insulator to the direction shown in the figure, and then install the mounting insulator, the
