2) Shake the stabilizer link ball joint stud several times.
3) Mount the self-locking nut on the ball joint, and then measure the ball joint rotating torque.
Standard value: 0.5 - 1.5 Nm (5 - 15 kg cm, 4.43 - 13.27 inch)
4) If the rotating torque exceeds the upper limit of standard value, replace the upper arm assembly.
5) Even if the rotating toque is below the lower limit of the standard value, the ball joint may be reused unless it has drag and excessive play.
