Product review (4 stars): Work but still rattle.
I am giving these 4 stars because one rattles a lot on spin. They did solve the terrible thumping and no spin problems however.  Our 11 year old washer is doing pretty well despite the rattle. Upon removal of the original dampers it was obvious they were totally shot  I don't know if I did something wrong in installation, if this is the way these are or if the rattly one if failing already. These are better than the originals but still a cheesy part in my opinion.

I'd say allow an hour for this repair. The access on the right side is more difficult than I expected. You might consider changing the suspension springs while you are in there.
