Product review (5 stars): Installation is not that bad. I had to replace the rods by myself
I was about to trash my washer after frustration with its constant vibration and banging until I came across this video on you tube (crAbY6vvdkA).  Installation is not that bad.  I had to replace the rods by myself, so it took a few trials before I figured the best way to replace the rods.  I had to replace 2 rods at a time.  I found it easier to reinstall the rods if the washer is laying on its side.  My washer is the Kenmore 20222(4yrs old).  So I assume these rods have a 4yr life.  Price is not bad either.
