Washer vibrates

On spin cycle washer vibrates real bad. Washer is level. Found a white powder in bottom panel. Washer vibrates no matter the size of load.
What can be the cause???:confused:

Most likely the snubber is getting worn. It is location number 14 on the transmission page of the breakdown.
