Be careful when you put the bearing back in as it's magnetic iirc and put on the wrong way round your abs light will stay on,assuming it's got abs of course but when we made the drums in plant the bearing had to be put in a certain way round so I assume all focii have abs.Check before you take the bearing out,needs to be pressed in and out and takes a lot of force to get it put/in.Circlip holds it in so need big circlip pliers to remove it.
