Lower Arm Ball Joint Rotation Starting Torque

Required Special Tool: 

• MB991006: Preload socket

1. Move the lower arm ball joint stud back and forth for several times, and measure the lower arm ball joint rotation starting torque using special tool MB991006.

   Standard value: 2.2 - 4.1 N.m (19 - 36 in-lb) 

2. If the measured value exceeds the standard range, replace the lower arm assembly (Refer to LOWER ARM  ).
3. Even if the measured value is within the standard range, check the lower arm ball joint that there is no looseness or gritty feeling. If there is no looseness or gritty feeling, it is judged as usable.
