Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
NOTE:
Before measurement, move ball stud at least ten times by hand to check for smooth movement.
• Hook a spring balance at the cutout on ball stud. Confirm spring
balance measurement value is within specifications when ball stud
begins moving.
• If it is outside the specified range, replace transverse link assem-
bly.
Axial End Play Inspection
• Move tip of ball stud in axial direction to check for looseness.
• If it is outside the specified range, replace transverse link assembly.
INSTALLATION
Installation is in the reverse order of removal.
• For tightening torque, refer to FSU-9, "
Component" .
• Perform final tightening of bolts and at the front suspension member installation position (rubber bushing)
under unladen conditions with tires on level ground. Check wheel alignment. Refer to RSU-2, "
