Product review (5 stars): Stop the wobble
I kept hearing a crunching sound when washing heavy items like blue jeans or bed comforters.  I came home from a business trip and couldn't get a simple load of shirts and pants to wash without unbalance error.  I installed all four  springs in less than 10 minutes and my problems are gone.  Any load imaginable runs perfect and the crunching sound is gone.  Great product !
