You may have one of three tie springs to the tub below broken. I had
this happen with another brand washer many years ago. --Phil

Hello,
My kenmore washer when it goes into the spin cycle begins to shake
violently. It will do this (to a lesser degree) when there aren't even
any clothes in it. How can I resolve this problem? Why is it doing
this? It shakes so much you have to sit on it to stop it from walking
away. Clothes are balanced...
