If the washer is making a loud noise the tub bearing might need to be replace. This is a very involved repair and will require disassembling most of the washer. The manufacturer recommends that if possible the complete outer tub and bearing be replaced rather than attempting to replace just the bearing in the tub. If the bearing is bad the problem is going to get worse very quickly and so either the drum and bearing will need to be replaced or the washing machine.
