Do-It-Yourself Story

After removing the pulsator (agitator) it was evident the spline was very worn. Also from looking at the diagram the washer below the pulsator (agitator) was missing since manufacture. I ordered a new washer, pulsator (agitator). The new pulsator appeared to have a steel spline unlike the original pulsator, a new cap because the old one had been removed so many times to tighten the screw down that it wouldn't stay tight any longer. I believe the problem was that the missing washer contributed to the pulsator (agitator) to wear out prematurely. Thanks to AppliancePartsPros' diagram, I was able to order the correct parts especially the washer. Also I asked for next day delivery and sure enough, the parts came the next day!!! I also asked LG for reimbursement for the parts and I am still waiting for their response.
