LOWER ARM BALL JOINT TURNING TORQUE CHECK

Required Special Tool:

• MB990326: Preload Socket

1. After shaking the ball joint stud several times, use special 

tool MB990326 to measure the turning torque of the lower 
ball joint.

Standard value: 1.0 

− 6.9 N⋅m (9 − 61 in-lb)

2. If the measured value exceeds the standard value, replace 

the lower arm ball joint.

3. If the measured value is lower than the standard value, 

measure the lower arm ball joint end play with a dial 
indicator.

4. If the end play exceeds a minimum scale of the dial indicator 

[0.01 mm (0.0004 inch)], replace the lower arm ball joint.
