1. After shaking the ball joint stud several times, install the nut

to the stud and use special tool MB990326 to measure the
turning torque of the ball joint.

Standard value: 1.5

− 7.9 N⋅m (13 − 70 in-lb)

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

the upper arm ball joint assembly.

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

check that the upper arm ball joint turns smoothly without
excessive play. If so, it is possible to use that ball joint.
