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 the preload socket (special tool: MB991006).

Standard value: 3.4 Nm (29 in-lb)

2. If the measured value exceeds the standard value, replace the lower arm assembly.
3. If the measured value is within the standard value, check that the lower arm ball joint has no looseness or gritty feeling. If there is looseness or gritty feeling, replace the lower arm assembly.
