If the washer is making a loud noise in the spin cycle, the clutch assembly might be worn out. The clutch assembly makes the connection between the transmission and the inner tub. It is designed to allow the tub to get up to the proper spin speed gradually. As the clutch wears out it may become loud during spin or just after the spin cycle finishes. The clutch is not repairable, if it is loud or not working properly it will need to be replaced.
