•	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 a piece of plastic hose, etc. (Refer to the picture below.)

1.	Remove the insulator dust cover (A).

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

3.	Using SST (0K546-F6100), Remove the self locking nut.

4.	Remove the insulator, spring pad, coil spring and dust cover from the strut assembly.

Inspection

1.	Check the strut bearing for wear and damage.

2.	Check the spring upper and lower seat for damage and deterioration.

3.	Compress and extend the piston rod (A) and check that there is no abnormal resistance or unusual sound during operation.

Disposal

1.	Fully extend the piston rod.

Drill a hole on the A section to remove gas from the cylinder in section (A).
