Whirlpool WP3951632 Lower Agitator OEM Part

I had to replace the drive shaft and the lower agitator. The motor coupling was also worn out. The repair was challenging because I had to rebuild the gear box. This step was really messy and I had to wait for the liquid gasket to set prior to completing the repair. Cleaning and prep of all of the parts tripled the repair time.

The diagnosis was the longest part of the repair, but I found out that the splines on the inside of the agitator had stripped out, so the matching splines on the drive shaft of the washer were not spinning the agitator as they should. I bought just the bottom part of the agitator from this site, and it matched perfectly with the old top part and the drive shaft of the washer. The actual repair just took 5 minutes.

Needed new lower agitator because spline stripped out after 3.5 years of in home use.

After reviewing some YouTube videos I was clear that my issue was most likely the agitator. I ordered a new one and BINGO!!! Great customer service from these guys and the part came next day which helped a bunch.

I removed it and replaced it with this product. I needed a 7/16" socket with extensions to loosen the center screw under the fabric softener holder, then removed the cap. I lifted the entire upper and lower center agitator stem to then be able to separate the top from the bottom where I replaced my worn/damaged lower half with this new product. I was slightly concerned it may not fit because the fit was very snug, but I managed to get it all put back together, run the machine and this product worked perfectly for my repair.
