I'm guessing you are referring to the inner bearing. Once the seal is removed from the back side of the hub, the bearing should fall out in your hand. You can get a seal puller tool or just use a screwdriver to pry the seal out. Make sure you replace bearings and the races as a set. They are matched for tolerance.
Just curious...How do you know you need to replace the bearings if you haven't removed them and inspected?
