Kenmore washer shakes violently during spin

Kenmore washer shakes violently during spin. Washer is balanced. It will shake even when no clothes are in it during the sping. Washer is level. We took it apart, the pads are all in place. Worked find until we moved it about 4 blocks to new home. Basket moves quite a bit just by moving it by hand. Any ideas?

I would lay the washer on it’s back and check the rear spring. Either it fell off, or the frame hole where the spring goes is rusted.
