Product review (4 stars): Guess it worked!
Washer has started vibrating more on the spin cycle than it use to.  Ordered these to see if they helped. They come with the new pins to hold them in and seem to be new product. The hardest part of replacing these is getting the old ones out, but the right size socket or open end wrench to compress the retainer and a hammer helps.  Guess it wasn't this that was the problem as they didn't fix the vibrations.
