Hook a spring balance at cutout on ball stud. Confirm spring bal-
ance measurement value is within specifications when ball stud
begins moving.
If it is outside the specified range, replace upper link assembly.
Rotating Torque Inspection
Attach mounting nut to ball stud. Make sure that rotating torque
is within specifications with a preload gauge [SST].
If it is outside the specified range, replace upper link assembly.
