nut.
11. Remove steering knuckle and wheel hub and bearing assembly fixing bolt.

INSPECTION AFTER REMOVAL
^
About the inspection for upper link, compression rod, steering outer socket, refer to "UPPER LINK", "COMPRESSION ROD", "POWER
STEERING GEAR AND LINKAGE".
Visual Inspection
^
Check steering knuckle and ball seat for deformation, cracks, and other damage. Replace steering knuckle and ball seat if cracks, deformation or
other damage is found.
^
Check ball joint boot for deformation, damage, and also for grease leakage. Replace steering knuckle assembly if cracks, deformation or also for
grease leakage is found.
Steering Knuckle Ball Joint Inspection
^
Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
CAUTION: Before measurement, move ball joint at least ten times by hand to check for smooth movement.
^
Hook spring scale at cotter pin mounting hole. Confirm spring scale measurement value is within specifications when ball stud begins moving.
Standard value
Swing force: 0.147 - 1.4 Nm (0.02 - 0.14 kg-m, 2 - 12 inch lbs.)
Measurement force: 2.23 - 21.2 N (0.22 - 2.16 kg, 0.50 - 4.77 lbs.)
If the value is outside the standard, replace steering knuckle.
Rotating Torque Inspection
^
Attach mounting nut to ball stud. Check that sliding torque is within specifications with a preload gauge (special service tool).
Standard value
Rotating torque: 0.147 - 1.4 Nm (0.02 - 0.14 kg-m, 2 - 12 inch lbs.)
^
If the value is outside the standard, replace steering knuckle.
Axial End Play Inspection
^
Move tip of ball joint in axial direction to check for looseness.
Standard value Axial end play: 0 mm (0 inch)
^
If the value is outside the standard, replace steering knuckle.
INSTALLATION
^
Refer to Exploded View for tightening torque. Tighten in the reverse order of removal.
CAUTION: Refer to component parts location and do not reuse non-reusable parts.
