3. Press out the axle.

4. After this, you can remove the bearing mounting flange and brake shield.

5. If the brake shield mounting bolt is being replaced, it can be pressed out of the flange.

6. Insert a new serrated bolt into the flange hole.

8. Install the brake shield and lock plate onto the axle shaft.
