Ball Joint: Testing and Inspection
INSPECTION1. Check the bushing for wear and deterioration.
2. Check the lower arm for bending or breakage.
3. Check the ball joint dust cover for cracks and damage.
4. Check all bolts for damage and deformation.
5. Check the lower arm ball joint for rotating torque.
^ 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 lb-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.
