Inspection and Adjustment


ADJUSTMENT BEFORE REMOVAL

Adjust neutral position of 4WAS front actuator. (With 4WAS) Work Procedure (Pattern 1).

INSPECTION AFTER REMOVAL

Appearance
Check the following items, and replace the part if necessary.
- Check suspension arm and bushing for deformation, cracks, and other damage.
- Check ball joint boot for cracks, damage, and leakage of grease.
Ball Joint Inspection
Manually move ball stud to confirm that it moves smoothly with no binding.
Swing Torque Inspection
1.Move the ball stud at least ten times by hand to check for smooth movement.





2.Hook spring balance (A) at cotter pin mounting hole. Confirm spring balance measurement value is within specifications when ball stud begins moving.
Swing torque: Rear Axle.
- If swing torque exceeds the standard range, replace suspension arm assembly.
Rotating Torque Inspection
1.Move the ball stud at least ten times by hand to check for smooth movement.





2.Attach the mounting nut to ball stud. Make sure that rotating torque is within the specifications with a preload gauge (A) [SST:
ST-3127S000 (J-25765-A)].
Rotating torque: Rear Axle.
- If rotating torque exceeds the standard range, replace suspension arm assembly.
Axial End Play Inspection
1.Move the ball stud at least ten times by hand to check for smooth movement.
2.
Move tip of ball stud in axial direction to check for looseness.
Axial end play: Rear Axle.
- If axial end play exceeds the standard range, replace suspension arm assembly.
