That wheel bearing is a press in type You have to remove the axle nut and washer. Then get a slide hammer with a hub attachment to remove the hub. Then pop the lower ball joint loose and the outter tie rod end loose. Then if there is a snap ring remove it then get a on car front wheel bearing tool to remove and replace the wheel bearing. Or remove the knuckle hub assembly and take it to have the new bearing pressed in and then you will have to get a alignment.
