^
Upper link and bushing for deformation, cracks or damage. Replace it if a malfunction is detected.
^
Ball joint boot for cracks or other damage, and also for grease leakage. Replace it if a malfunction is detected.
Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.

NOTE: Before measurement, move ball stud at least ten times by hand to check for smooth movement.
^
Hook a spring balance at cutout on ball stud. Confirm spring balance measurement value is within specifications when ball stud begins moving.
Swing torque: 0 - 2.0 Nm (0 - 0.2 kg-m, 0 - 17 in-lb)
Spring balance measurement: 0 - 61.5 N (0 - 6.2 kg, 0 - 13.6 lb)
^
If it is outside the specified range, replace upper link assembly.
Rotating Torque Inspection
^
Attach mounting nut to ball stud. Make sure that rotating torque is within specifications with a preload gauge [SST].
Rotating torque: 0 - 2.0 Nm (0 - 0.2 kg-m, 0 - 17 in-lb)
^
If it is outside the specified range, replace upper link assembly.
Axial End Play Inspection
