This package contains a new set of six springs. The suspension springs in your washer connect to the bottom of tub, and help to hold it in place. If your washer tub shakes, or moves around a lot during operation, it could mean that one or more of your springs are damaged or stretched. You will need to access the bottom of the tub for this repair by removing the front (and possibly the rear) panel. You will also need a pair of locking pliers to remove the old springs and reconnect the new ones. It is recommended to apply a small amount of grease to the bottom of the new springs before you reconnect them to the washer tub.
