8. Use a ball joint remover to remove steering outer socket from
steering knuckle. Be careful not to damage ball joint boot.
CAUTION:
Tighten temporarily mounting nut to prevent damage to
threads and to prevent ball joint remover (SST) from com-
ing off.
9. After removing upper link, transverse link, compression rod and
cotter pin at steering knuckle, loosen mounting nut.
10. Use a ball joint remover (suitable tool) to remove upper link,
transverse link and compression rod from steering knuckle. Be
careful not to damage ball joint boot.
CAUTION:
Tighten temporarily mounting nut to prevent damage to threads and to prevent ball joint remover
(suitable tool) from coming off.
11. Remove steering knuckle and wheel hub and bearing assembly fixing bolt.
12. Remove wheel hub and bearing assembly from steering knuckle.
INSPECTION AFTER REMOVAL
About the inspection for upper link, compression rod, steering outer socket, refer to FSU-14, "UPPER
LINK" , FSU-16, "COMPRESSION ROD" , PS-17, "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 balance at cotter pin mounting hole. Confirm spring
balance measurement value is within specifications when ball
stud begins moving.
If it is outside the standard, replace steering knuckle.
Rotating Torque Inspection
Attach mounting nut to ball stud. Check that rotating torque is
within specifications with a preload gauge.
If it is outside the standard, replace steering knuckle.
