- If there is a crack in the dust cover, replace the ball joint assembly.
- Shake the ball joint stud several times.
- Measure the ball joint rotating torque.
  Standard value
  
  2.0~3.5 Nm (20~35 kgf.cm, 1.48~2.58 lbf.ft)
- If the rotating torque is above the upper limit of the standard value, replace the ball joint assembly.
- Even if the rotating torque is below the lower limit of the standard value, the ball joint may be reused unless it has drag and excessive play.
