New spider arm and balance ring.. Required complete disassembly of the washer. Videos on your website were very helpful. I am 67 years old and not in the best health, but by taking my time and paying attention to detail I was able to complete the task by myself with only moderate difficulty. No special tools are required. Would recommend using six point sockets to avoid rounding off the bolt heads on the spider arm. The person in one review stated the spider arm was a part designed to fail and I completely agree with him. Over time the spider arm will begin to disintegrate because of the poor quality of the metal. Our washer was used a average of one to two loads a week. I did as one reviewer suggested. I put 3 coats of epoxy resin paint on the new spider arm before installation Time will tell if it will help.
