Product review (5 stars): Great replacement part for GE Select 3500 series washing machine.
If your agitator is making funny noises or not spinning then check out the hub underneath it. If the splines are gone then you need this part and the agitator (GE WH43X10034). The install goes pretty quickly with a little patience if your old bolt was rusted like mine. To remove the old hub start with getting the bolt out. If the socket slips around the edges try a 12 point of the same size or the next size down in SAE or metric. Mine didn't budge with any due to the rust so I chipped down the plastic around the bolt until I could get visegrips on the lower shoulder of the bolt. It came right out and then the hub was stuck too. I located the splines and then drilled out the plastic just outside the splines to split it. It came right off and after a little clean up I installed the new one. It took me about 30 minutes after diagnosing the issues and gathering the tools.
