Control Link and Upper Arm Pillow Ball Bushing Rotation Starting Torque Check [GTS]

CONTROL LINK AND UPPER ARM PILLOW BALL BUSHING ROTATION STARTING TORQUE CHECK [GTS]

Required Special Tool:
^ MB990326: Preload socket





1. Insert the bolts to the control link and the upper arm pillow ball bushing (vehicle body outside bushing) respectively, and install the nuts with the washers from the opposite side. Rotate the inner cylinder (including washer) for several turns, and measure the rotation starting torque of the control link and the upper arm pillow ball bushing respectively using the special tool MB990326.

Standard value: 2.0-3.5 Nm (17.7-31.0 in-lb)

2. When the measured value exceeds the standard range, replace the control link or the upper arm pillow ball bushing.
3. When the measured value is less than the standard range, check that the control link and the upper arm ball joint has no looseness or gritty feeling. If there is no looseness or gritty feeling, it is judged as usable.
