Always use the support point specified for lifting.
Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for
unavoidable reasons, support at the rear axle jacking point with transmission jack or similar tool
before starting work, in preparation for the backward shift of center of gravity.
For supporting points for lifting and jacking point at rear axle, refer to GI-42, "Garage Jack and
Safety Stand and 2-Pole Lift" .

(wear, damage) are normal.
WHEEL BEARING INSPECTION
Move wheel hub and bearing assembly in the axial direction by hand. Make sure there is no looseness of
wheel bearing.
Rotate wheel hub and make sure that is no unusual noise or other irregular conditions. If there is any of
irregular conditions, replace wheel hub and bearing assembly

block, and then remove hub lock nut. (AWD)
CAUTION:
Do not place drive shaft joint at an extreme angle. Also be
careful not to overextend slide joint.
Do not allow drive shaft to hang down without support for
housing (or joint sub-assembly), shaft and the other
parts.
NOTE:
Use a puller (suitable tool) if wheel hub and bearing assembly
and drive shaft cannot be separated even after performing the
above procedure.
8. Remove wheel hub and bearing assembly mounting bolts, and then remove splash guard and wheel hub
and bearing assembly from steering knuckle.
Steering knuckle
1. Refer to the procedure from 1 to 7 in “Wheel Hub and Bearing Assembly” FA X - 5 , "REMOVAL" .
2. Remove cotter pin (1), and then loosen the nut.
3. Remove steering outer socket (2) from steering knuckle (3) so
as not to damage ball joint boot (4) using the ball joint remover
(suitable tool).
CAUTION:
Temporarily tighten the nut to prevent damage to threads
and to prevent the ball joint remover (suitable tool) from
suddenly coming off.
4. Remove cotter pin of transverse link and steering knuckle, and
then loosen nut.
5. Remove transverse link from steering knuckle so as not to dam-
age ball joint boot using the ball joint remover (suitable tool).
CAUTION:
Temporarily tighten the nut to prevent damage to threads and to prevent ball joint remover (suit-
able tool) from suddenly coming off.
6. Remove fixing nut and bolt with a power tool, and then remove steering knuckle from upper link. Refer to
FSU-8, "
Components" .
7. Remove wheel hub and bearing assembly mounting bolts, and then remove splash guard and wheel hub
and bearing assembly from steering knuckle.
INSPECTION AFTER REMOVAL
Check components for deformation, cracks, and other damage. Replace if there are.
Ball Joint Inspection
Check boots of transverse link and steering outer socket ball joint for breakage, axial play, and torque. Refer to
FSU-14, "
INSPECTION AFTER REMOVAL" , “TRANSVERSE LINK”, PS-22, "INSPECTION AFTER DISAS-
SEMBLY" , “POWER STEERING GEAR”.

Adjust neutral position of steering angle sensor after checking the wheel alignment. Refer to BRC-6,
"Adjustment of Steering Angle Sensor Neutral Position" .
Check wheel sensor harness for proper connection. Refer to BRC-57, "WHEEL SENSOR" .
Assemble disc rotor and wheel hub and bearing assembly by
aligning each matching mark as shown in the figure when install-
ing disc rotor.
NOTE:
Refer to BR-28, "
