washer moving 3 ft during the spin cycle sounding like elephants running through the house

Removed back panel to remove tub from shell. Unscrewed the brackets holding the springs. Used screw driver to pop out pads with hammer onto screw driver. Cleaned out tub and put grease on springs where they attach to bracket. Replaced panel and ran machine to find a leak. Took machine apart again to find the knocking of the tub against the back panel caused a whole in the plastic tub. Silicon and mechanical tape. Washer works fine for now.
