Product review (5 stars): Runs like a champ now
We think somehow in transporting a used washer we got from a friend that one of these pads fell out because it was completely missing and worked fine when he had it. Over time after we installed it, the washer would shake more and more violently, walking across the floor, and eventually banging against its sides. At that point we took it apart and found one of these pads was gone and had worn the metal into dusty graphite-like mess on the floor. We got these pads, the rectangular suspension pads, and springs in order to reach the $25 add-on program requirements, and now the washer is running so smoothly that it barely makes a sound. Amazing what one missing pad can do to make the thing shake so violently.

Some people in the reviews say that you can replace the pads without taking the tub off, which is probably true. However, this washer was ten years old and had probably never been cleaned, and there were rings of build up dirty and nasty-s inside the plastic liner (you're washing your clothes in that muck!) so we went ahead and took it apart and cleaned it and greased the moving parts in the drive shaft. It's not hard to take apart (we easily found a video that showed how to replace these pads and it was super easy to follow and do) and we're glad we did it that way. Only kicker is the need for a spanner wrench, but if you're careful, you can take and remove the spanner nut with just a hammer and wedge by tapping each notch a little at a time, going around it in a circular motion.
