Product review (5 stars): Difficult install but it works.
If your washing machine is older and can't seem to balance a load despite being leveled this is probably what you need. if you open up the washing machine and see white powder or dust at the bottom this is the part you need. Installation of this is pretty challenging because you have to take the drum put of the machine and most likely all of the screws will be rusted in place. Despite the difficult installation this $5 part will save you $500 on a new washer, since putting this into our machine it balanced every load, something it hadn't done for months before.
