Product review (5 stars): Works great! - also change the nearby skid pads so the new seal will last longer
I used this with some old-school gasket shellac (as seen on YouTube). Paint the outer seal groove, fold/press the seal into the tub, rotate the seal a half-turn to ensure everything is fully in place and straight, slide tub onto the center post using a bit of silicone lube, then let dry for an hour or so. If you're into the washer this far, take an extra 5 min and also replace the 2 sets of 3-each nylon skid pads (<a data-hook="product-link-linked" class="a-link-normal" href="/Whirlpool-Part-Number-285219-PAD/dp/B001DPFKKG/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Whirlpool Part Number 285219: PAD</a>&nbsp;and&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Whirlpool-285744-Pads/dp/B00DM8KFOI/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Whirlpool 285744 Pads</a>&nbsp;so that the tub won't shake as much, which is usually what makes this seal start to leak. Keep these direct-drive washers going - they are easy & cheap to fix, very reliable, and even get your clothes clean. No pillows, shoes, or other unbalanced loads though, since those really tear up this type of washer.
