I had a bad vibration in the rinse cycle, which caused the coupler to break. I've replace the coupler, but whenb I removed the cabinet, I noticed a spring lying on the ground under the washer.

I see the three larger diameter "suspension springs" and those are in place. The spring is a fourth, and smaller diameter spring, which has one short end and one 3" long "tail". I have no idea where this fits, if it was the initial cause of my vibration problem, or a result of the problem.

I see the sping in the diagrams for parts, but don't know what it's called or where it hooks in. Any help on location would be appreciated!

Thank you in advance
