balance measurement value is within the specifications when ball
stud begins moving.

• If it is outside the specified range, replace suspension arm assem-

bly.

Rotating Torque Inspection

• Attach mounting nut to ball stud. Make sure rotating torque is

within the specifications with a preload gauge (SST).

• If it is outside the specified range, replace suspension arm assem-

bly.

Axial End Play Inspection
