LOWER ARM BALL JOINT BREAKAWAY TORQUE CHECK
Required Special Tool
- MB990326: Preload Socket
Scheme 1
- Move the ball joint stud several times and install the lower arm nut on the stud. Using special tool MB990326, measure the ball joint breakaway torque. Standard value: 3.5-6.9 N. m (31-61 in-lb)
- If the measured value is not within the standard value, or if the ball joint is difficult to turn or does not turn smoothly, replace the lower arm assembly.
STABILIZER LINK BALL JOINT BREAKAWAY TORQUE CHECK
Required Special Tool
- MB990326: Preload Socket
Scheme 2
- After shaking the ball joint stud several times, install the nut to the stud and use special tool MB990326 to measure the breakaway torque of the ball joint. Standard value: 3.4-9.0 N. m (30-80 in-lb)
- When the measured value exceeds the standard value, replace the stabilizer link.
- 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 re-use that ball joint.
