Disassembly and Assembly
INFOID:0000000009721405
DISASSEMBLY
CAUTION:
Never damage strut assembly piston rod when removing components from strut assembly.
1.
Install strut attachment (A) [SST: ST35652000 (
—
)] 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.
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 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 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 onto strut mounting insulator.
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 compressor is securely attached to coil spring.
Compress coil spring.
• 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.

5.
Install strut mounting bearing and strut mounting insulator with bound bumper to strut.
• Installation position of strut mounting insulator is shown in the
figure.
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 (commercial service
tool), and remove coil spring.
CAUTION:
Loosen while making sure coil spring attachment position does not move.
8.
Remove the strut attachment [SST: ST35652000 (
—
)] from strut assembly.
Inspection
INFOID:0000000009721406
INSPECTION AFTER DISASSEMBLY
Strut
Check the following items, and replace the parts if necessary.
• Strut for deformation, cracks or damage.
• Piston rod for damage, uneven wear or distortion.
• Oil leakage.
Strut Mounting Insulator and Rubber Parts Inspection
Check strut mounting insulator for cracks and rubber parts for wear. Replace it if necessary.
Coil Spring
Check coil spring for cracks, wear or damage. Replace it if necessary.
INSPECTION AFTER INSTALLATION
1.
Check wheel sensor harness for proper connector. Refer to
BRC-123, "FRONT WHEEL SENSOR :
.
2.
Check wheel alignment. Refer to
3.
Adjust neutral position of steering angle sensor. Refer to
BRC-9, "ADJUSTMENT OF STEERING ANGLE
SENSOR NEUTRAL POSITION : Special Repair Requirement"
.
Disposal
INFOID:0000000009721407
1.
Set strut assembly horizontally with the piston rod fully extended.
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.
