FRONT COIL SPRING AND STRUT
• Install strut assembly with the identification mark (A) of mounting
insulator faced forward of the vehicle and the arrow (B) faced out-
side.
NOTE:
The identification mark “0” shows the right mounting insulator and
“1” shows left.
• Perform final tightening of fixing parts at the vehicle installation
position (rubber bushing), under unladen conditions with tires on
level ground.
• Perform inspection after installation. Refer to
.
• After replacing the strut, always follow the disposal procedure to
discard the strut. Refer to
Disassembly and Assembly
INFOID:0000000010119432
DISASSEMBLY
CAUTION:
Do not damage strut assembly piston rod when removing components from strut assembly.
1. Remove the cap.
2. Install Tool (A) to strut assembly 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.
3. Using a spring compressor (A), compress 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.
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 mounting insulator, mounting bearing, and bound
bumper from strut.
6. 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.
7. Remove lower rubber seat.
8. Remove Tool from strut assembly.
9. Perform inspection after disassembly. Refer to
ASSEMBLY
CAUTION:
Do not damage strut assembly piston rod when installing components from strut assembly.

When installing the strut attachment to strut assembly, wrap a shop cloth around strut to protect
from damage.
2. Install lower rubber seat.
3. Compress coil spring using a spring compressor, and install it onto strut assembly.
CAUTION:
• Be sure a compressor is securely attached to coil spring. Compress coil spring.
• Be careful with the vertical direction of the coil spring.
• Align the lower end of coil spring (1) with (A) of lower rub-
ber seat (2) as shown.
4. Apply soapy water to bound bumper.
CAUTION:
Do not use machine oil.
5. Insert bound bumper into mounting insulator.
6. Install mounting bearing.
CAUTION:
Do not apply oils, such as grease, when installing the
mounting bearing.
7. Check the location of identification mark (A) of the mounting
insulator and install it with the arrow (B) faced outside of the
vehicle to the strut.
NOTE:
The identification mark “0” shows right mounting insulator and
“1” shows left.
8. Secure piston rod tip so that piston rod does not turn, then
tighten piston rod lock nut with specified torque.
CAUTION:
Do not reuse piston rod lock nut.
9. Gradually release a spring compressor (A), and remove coil
spring.
CAUTION:
Loosen while making sure coil spring attachment position
does not move.

Inspection
INFOID:0000000010119433
INSPECTION AFTER DISASSEMBLY
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-158, "FRONT WHEEL SENSOR :
.
2. Check wheel alignment. Refer to
Disposal
INFOID:0000000010119434
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 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 the direction show by arrow.
• Drill directly to the outer tube avoiding brackets.
• The gas is clear, colorless, odorless, and harmless.
