Ball Joint Breakaway Torque Check





1. After shaking the ball joint stud several times, install the nut to the stud and use the special tool to measure the breakaway torque of the ball joint.

Compression lower arm ball joint
Standard value: 0.5 - 2.5 Nm (4 - 22 inch lbs.)
Lateral lower arm ball joint
Standard value: 1.5 Nm (13 inch lbs.) or less

2. When the measured value exceeds the standard value, replace the compression lower arm assembly or lateral lower arm assembly.
3. When the measured value is lower than the standard value, check that the ball joint turns smoothly without excessive play. If so, it is possible to use that ball joint.

Ball Joint Dust Cover Check
