INSPECTION AFTER REMOVAL
Visual Inspection

Check suspension arm and bushing for deformation, cracks, or damage. If any non-standard condition is
found, replace it.

Check boot of ball joint for cracks, or damage, and also for grease leakage.
Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
NOTE:
Before measuring, move ball joint at least ten times by hand to check for smooth movement.

Hook a spring scale at cotter pin mounting hole. Confirm spring
scale measurement value is within the specifications when ball
stud begins moving.

If it is outside the specified range, replace suspension arm
assembly.
Rotating Torque Inspection

Attach mounting nut to ball stud. Make sure rotating torque is
within the specifications with a preload gauge (SST).

If it is outside the specified range, replace suspension arm
assembly.
Axial End Play Inspection

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

If it is outside the specified range, replace suspension arm assembly.Swing torque:
0.5 − 3.4 N·m (0.06 − 0.34 kg-m, 5 − 30 in-lb)
