Product review (4 stars): Good part, and costs <third of replacing entire drum, but only if you can get your old one off....
small part of a long story but ultimately successful repair.... washer was knocking during spin, and like most people I thought it was the bearings. I ordered all 3 parts and replaced them even though they looked fine... but it was the stem of the spider that was rusted at the base and needed replacing. I ordered this part, which would have fit perfectly, except that the screws holding the old spider in the drum would spin but not back out. Just too much gunk in the screw holes - could not unscrew or pull them out. So had to order the entire inner drum (found for <200 elsewhere), which included the spider already on.

What I wish I knew before I took 10 hours to repair the washer, from start to finish, including time cleaning, and not including the time waiting for parts to be delivered:
1. order bearings, all 3 parts - about 60
2. order spider - about 60 (may as well, and hope that it comes out) OR EVEN BETTER order inner drum with spider&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/LG-Electronics-3045ER1006E-Washing-Machine-Inner-Tub-Drum-Assembly/dp/B00AUDA8R2/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">LG Electronics 3045ER1006E Washing Machine Inner Tub Drum Assembly</a>

4. order rubber gasket - about 50 (was black and disgusting anyway, and yours probably is, too) - make sure you check the bottom to see if you have the one with the drain or without the drain, mine did not&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/LG-Electronics-4986ER0004G-Washing-Machine-Door-Bo/dp/B00AF7UY9U/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">LG Electronics 4986ER0004G Washing Machine Door Bo</a>
