2. Without disassembling the hydraulic lines, remove the torque member bolts using power tool. Then repo-
sition the torque member and brake caliper assembly aside with wire. Refer to BR-24, "
FRONT DISC
BRAKE" .
CAUTION:
Do not depress brake pedal while brake caliper is removed.
3. Put alignment marks on disc rotor and wheel hub and bearing
assembly, then remove disc rotor.
4. Remove wheel sensor from steering knuckle. Refer to BRC-33, "
WHEEL SENSORS" .
CAUTION:
Do not pull on wheel sensor harness.
5. Loosen steering outer socket (1) nut.
6. Remove steering outer socket (1) from steering knuckle (2) so
as not to damage ball joint (3) boot using ball joint remover or
suitable tool.
CAUTION:
Temporarily leave the outer socket nut installed to prevent
damage to threads and to prevent the ball joint remover or
suitable tool from suddenly coming off.
7. Remove transverse link ball joint nut and bolt. Then, remove transverse link from steering knuckle.
8. Remove cotter pin, then loosen hub lock nut using power tool.
CAUTION:
Temporarily leave the hub lock nut installed to prevent damage to threads.
9. Separate the drive shaft from the wheel hub and bearing assem-
bly by lightly tapping the end of the drive shaft using a hammer
or suitable tool, and then remove hub lock nut.
NOTE:
Use a suitable puller if wheel hub and bearing assembly and
drive shaft cannot be separated after performing the above pro-
cedure.
10. Remove the drive shaft from the wheel hub and bearing assem-
bly and support the drive shaft.
CAUTION:

Do not apply an excessive angle to drive shaft joint when
removing from the wheel hub and bearing assembly,

Do not excessively extend slide joint.

Do not allow drive shaft to hang down. Support the entire drive shaft.
11. Remove wheel hub and bearing assembly bolts, and then remove splash guard and wheel hub and bear-
ing assembly from steering knuckle.
