Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
1. Move the ball joint at least ten times by hand to check for smooth movement.
2. 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 upper link assem- bly.
Rotating Torque Inspection
1. Move the ball joint at least ten times by hand to check for smooth movement.
2. Attach mounting nut to ball stud. Check that rotating torque is
within specifications with a preload gauge [SST: 3127S000 (J-
25765-A)] (A).
 If rotating torque exceeds standard range, replace lower link assembly.
Axial End Play Inspection
1. Move the ball joint at least ten times by hand to check for smooth movement.
2. Move tip of ball stud in axial direction to check for looseness.
 If axial end play exceeds standard range, replace upper link assembly.
INSPECTION AFTER INSTALLATION
1. Check wheel sensor harness for proper connection. Refer to BRC-134, "FRONT WHEEL SENSOR :
Exploded View".
2. Check wheel alignment. Refer to FSU-7, "
Inspection".
3. Adjust neutral position of steering angle sensor. Refer to BRC-64, "
Work Procedure".
Swing torque : Refer to
FSU-21, "
Ball Joint".

ServiceINFOID:0000000006113090
 Disconnect battery negative terminal in advance.
 Disconnect air bag system line in advance.
 Never tamper with or force air bag lid open, as this may adversely affect air bag performance.
 Be careful not to scratch pad and other parts.
 When removing or disassembling any part, be careful not to damage or deform it. Protect parts, that may get
in the way with a shop cloth.
 When removing parts with a screwdriver or other tool, cover the tool surface with vinyl tape to protect parts.
 Keep removed parts protected with a shop cloth.
 If a clip is deformed or damaged, replace it.
 If an unreusable part is removed, replace it with a new one.
 Tighten bolts and nuts firmly to the specified torque.
 After reassembly is complete, check that each part functions correctly.
 Remove stains via the following procedure.
Water-soluble stains:
Dip a soft cloth in warm water, and then squeeze it tightly. After wiping off the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3%), dip the cloth, then wipe off the stain with the
cloth. Next, dip the cloth in fresh water and squeeze it tightly. Then wipe off the detergent completely. Then
wipe the area with a soft dry cloth.
 Never use any organic solvent, such as thinner or benzine.
