1. Move the upper arm ball joint stud back and forth for several 

times, then measure the upper arm ball joint rotation starting 
torque using the special tool MB991006.

Standard value: 3.4 N

⋅ m (30.0 in-lb) or less

2. When the measured value exceeds the standard range, 

replace the upper arm assembly.
