NOTE:
Before measuring, move ball joint at least ten times by hand to check for smooth movement.
 Hook a spring balance at cotter pin mounting hole. Confirm spring balance measurement value is withi n the specifications when ball
stud begins moving.
 If it is outside the specified r ange, 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 r ange, replace suspension arm assem-
bly.
Axial End Play Inspection
 Move tip of ball joint in axial direction to check for looseness. Swing torque:
0.5
− 3.4 N·m (0.06 − 0.34 kg-m, 5 − 30 in-lb)
