White fluffy residue appeared under washer. Unbalanced banging during spin cycle

Parts needed: Snubber Ring and 6 Springs (don't put the old springs back)
Unlug the AC cord, open the top from the front it snaps open with a little force and hinges on the back, remove the 2 screws on the front cover and take it off, tip the washer and remove the belt, take off the pump hose from the back It was not necessary to remove the back cover. Remove the little hose going to the basket from the control module. Remove the 6 springs and lift the complete drum out of the waser and turn it upside down. You can see the plastic snubber ring that is worn, loosen the 6 screws just enough to get the old ring out and the new one in. WARNING: DO NOT TAKE THE SCREWS ALL THE WAY OUT OR THE BRAKE ASSEMBLY WILL RELEASE AND A SPECIAL TOOL IS NEEDED TO PUT IT BACK. Seriously! Install the new ring, center and tighten the screws. Put the tub back in. I found it handy to support the tub with a 2x3 to get the springs back in. Connect hoses back up. It really isn’t that bad, a couple of scraped knuckles.
