If abnormal conditions are discovered during
inspection, go to Step 6. If there are no abnormal
conditions,  reassemble the front disc rotor and
caliper.

NOTE:  Hub, wheel bearing and spindle is integrated to
the hub unit bearing so it must not be disassembled.  If
it has abnormal rattle or noize, replace the hub unit
bearing.

6. Remove the ABS sensor connector.

7. Remove the 4 bolts fixing the hub unit bearing to the

knuckle.

Apply penetrating oil to the bearing and knuckle contact
surfaces if the surfaces are stuck together because of
rust.

8. Temporarily install long bolts to 2 of the fixing bolt

holes (the bolts must have the same diameter and
thread width).

9. Strike the long bolts with a hammer to loosen and

remove the hub unit bearing from the knuckle.

Take care not to drop the bearing.

10. If necessary, replace the wheel pin in the following

manner.

• Place hub on a suitable work surface and remove

wheel studs, as required, using a hammer.

If there is rust on the bearing and knuckle contact
surfaces, use sandpaper to remove it before installation.

3. Install the ABS sensor connector.

4. Install the disc rotor.

the work process.

Refer to Front disc caliper assembly in Section 5C of
this Manual.

4. Remove the disk rotor.

Apply penetrating oil to the bearing and disc rotor
contact surfaces if the surfaces are stuck together
because of rust.

5. Inspect the hub unit bearing. Refer to inspection

below.

6. Use a dial gauge to measure the bearing axial rattle.
