Replacing la z boy non seat spring?

Hello,
I have an 11 year old La Z Boy rocker recliner. one of the non seat springs under the seat has broken. They sent me the replacement spring ( actually two of them) and some clips, and told me it was a very easy repair. Although one end was easy to get at, the other is buried under the edge of the frame and is very hard to get at. Can anyone walk me through the proper steps to replace this spring. Since they told me it was easy, I assume I'm missing something. Thanks
