INSPECTION AFTER REMOVAL
Visual Inspection

Check transverse link and bushing for deformation, cracks, or damage. If any non-standard condition is
found, replace it.

Check boot of ball joint for cracks, or other damage, and also for grease leakage. If any non-standard con-
dition is found, replace it.
Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.

Swing Torque Inspection
NOTE:
Before measurement, move ball joint at least ten times by hand to check for smooth movement.

Hook spring scale at ball stud. Confirm spring scale measure-
ment value is within the specifications when ball stud begins
moving.

If it is outside the specified range, replace transverse link
assembly.
Rotating Torque Inspection

Attach mounting nut to ball stud. Check that rotating torque is
within the specifications with a preload gauge (SST).

If it is outside the specified range, replace transverse link
assembly.
Axial End Play Inspection

Move tip of ball joint in axial direction to check for looseness.

If it is outside the specified range, replace transverse link assembly.
INSTALLATION

Refer to FSU-8, "Components" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

After removing/installing or replacing suspension components, check wheel alignment. Refer to FSU-6,
"Wheel Alignment Inspection" .

After adjusting wheel alignment, adjust neutral position of steering angle sensor. Refer to BRC-6, "Adjust-
ment of Steering Angle Sensor Neutral Position" . Swing torque:
Less than 0.5 − 4.9 N·m (0.06 − 0.49 kg-m, 5 − 43 in-lb)
Measure value of spring scale:
Less than 0.5 − 4.9 N·m (0.06 − 0.49 kg-m, 5 − 43 in-lb)
