Disassembly
   
•
When compressing the coil spring, be cautious as there may be corrosion due to damage to the coil spring painting.
In order to avoid such painting damage, compress by putting over the waste hose, etc. (Refer to the picture below.)

1.
Remove the insulator cap (A).

2.
Using the spring compressor, compress the coil spring (A).
Do not compress the spring more than necessary.

3.
Loosen the self locking nut from the strut by using the SST (09456-3X100).

4.
Remove the insulator, coil spring and dust cover from the strut.
Inspection
1.
Check the strut bearing for wear and damage.
2.
Check the rubber part for damage and deterioration.
3.
Compress and extend the strut rod (A) and check that there is no abnormal resistance or unusual sound during operation.

Disposal
1.
Fully extend the strut rod.
2.
Drill a hole on the A section to remove gas from the cylinder.

   
•
The gases emitted are colorless, odorless, and harmless.
Reassembly
1.
Install the insulator, spring seat, coil spring and dust cover from the strut.
2.
The spring (A) is compressed using a spring compressor until there is some tension in the spring.

3.
Install the self locking nut from the strut by using the SST (09546-3X100).
   
•
Do not reuse the self locking nut.
Tightening torque :
98.0 - 107.8 N.m (10.0 - 11.0 kgf.m, 72.3 - 79.6 lb-ft)

Installation
1.
To install, reverse the removal procedures.
2.
Check the alignment.
