1.

Set shock absorber 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.

Manually move ball stud to confirm it moves smoothly with no binding.

Swing Torque Inspection

NOTE:
Before measurement, move ball stud at least ten times by hand to check for smooth movement.
• Hook a spring balance (A) at cotter pin mounting hole. Confirm

spring balance measurement value is within specifications when
ball stud begins moving.

- If swing torque exceeds standard range, replace transverse link

assembly.

Rotating Torque Inspection

• Attach mounting nut to ball stud. Make sure that rotating torque is

within specifications with a preload gauge (A) [SST: 3127S000 (J-
25765-A)]. 

- If rotating torque exceeds standard range, replace transverse link

assembly.

Axial End Play Inspection

• Move tip of ball stud in axial direction to check for looseness.

- If axial end play exceeds standard range, replace transverse link assembly.

INSPECTION AFTER INSTALLATION
