Product review (5 stars): Use this to stop your machine from insane banging and walking!
For months my machine would bang on the spin cycle as if it were possessed. It would bang so hard and loud that it would "walk" several inches. Usually this would be because of an off-balance load however even after shifting clothes around it still happened. I ran an empty load and found there was a very slight vibration. Checking the service manual, it said if you push down on the basket and it bounces up and down more than once then the suspension needs to be replaced. So I got the kit. Arrived quickly. Managed to change out all four rods in less than an hour all by myself.
After the rods are replaced, the service manual said the machine needs to be calibrated. So I did that. Ran a wash cycle. Lo and behold! No more banging! No more mysterious machine movement!

This is an excellent product and a necessary part of standard maintenance for your machine. SO glad I got it!
