REMOVAL

1. Remove the wheel and tire assembly using power tool. Refer to 

WT-39, "Adjustment"

.

2. Remove brake hose lock plate from strut assembly.
3. Remove stabilizer connecting rod from strut assembly. Refer to 

FSU-14, "Removal and Installation"

.

4. Remove strut bolts and nuts from steering knuckle.
5. Remove stopper insulator lock nut and stopper insulator.
6. Remove strut assembly.

INSTALLATION

Installation is in the reverse order of removal.

• Secure the head of strut piston rod to keep it from rotating, then tighten the stopper insulator lock nut to the

specified torque.

CAUTION:

Do not reuse stopper insulator lock nut.

• Do not reuse the nuts that secure the strut to the steering knuckle and stopper insulator lock nut.

• Perform inspection after installation. Refer to 

FSU-6, "Inspection and Adjustment"

.

• After replacing the strut assembly, always follow the disposal procedure to discard the strut assembly. Refer

to 

FSU-10, "Disposal"

.

Disassembly and Assembly

INFOID:0000000009267402

DISASSEMBLY

CAUTION:

Do not damage strut assembly piston rod when removing components from strut assembly.
1. Remove strut mounting insulator.
2. Install Tool (A) to strut assembly and secure it in a vise.

CAUTION:

When installing the Tool to strut assembly, wrap a shop

cloth around strut to protect from damage.

3. Using a suitable tool, compress coil spring between spring upper

seat and lower seat (strut assembly) until coil spring is free.

CAUTION:

Be sure the tool is securely attached to the coil spring

before compressing 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. After removing coil spring with a spring compressor, then gradually release a spring compressor.

CAUTION:

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

8. Remove the Tool from strut.

9. If necessary, remove strut mounting bearing (1) from spring

upper seat (2), using a Tool (A).

CAUTION:

Do not disassemble the strut mounting bearing unless

damage exists.

10. Perform inspection after disassembly. Refer to 

FSU-6, "Inspec-

tion and Adjustment"

.

INSPECTION AFTER DISASSEMBLY

Strut Inspection

Check the following:

• Strut for deformation, cracks or damage, and replace it if necessary.

• Piston rod for damage, uneven wear or distortion, and replace it if necessary.

• For oil leakage, and replace it if necessary.

Strut Mounting Insulator and Rubber Parts Inspection

Check strut mounting insulator for cracks and rubber parts for wear. Replace it if malfunction is detected.

FRONT COIL SPRING AND STRUT

Coil Spring Inspection

Check coil spring for cracks, wear or damage, and replace it if necessary.

ASSEMBLY

1. Install Tool (A) 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. Apply soapy water to bound bumper.

CAUTION:

Do not use machine oil.

3. Insert bound bumper into spring upper seat.
4. Compress coil spring using a spring compressor (commercial

service tool), and install it onto strut assembly.

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 Tool (A) from strut assembly.

9. Install strut mounting insulator.

Disposal

INFOID:0000000009267403

• 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.
