Kenmore he2plus vibrate very badly, it is level how do i fix this

My HE2T was making a horrendous sound during the spin cycle. It was making a loud clacking sound and the machine was moving all over the place.

There are two things to check. The first is that the feet are on the floor and the machine is level. The second is a bit more complex. Remove the three screws that hold the lower panel. Underneath the drum on each of the four corners are suspension rods. One side is attached to the drum and the other side is bolted to the bottom of the washer. My bolts loosened up which allowed the suspension rods to clack back up and down as the drum spun. You'll need to tighten those bolts very tight and then give it another try.

Attached on the inside of that cover is the troubleshooting guide. There is a manual diagnostic mode and you can step it to the spin cycle so that you can test the spin balance without having to run through a full cycle. Make sure you have some clothes in there during the test.
