'02 4runner seats creaking noise

[Thundercloud]

I have a '02 4runner that has a creaking noise in the seats. I took it to the dealership and they sent it to a shop to have the seats redone. Now that I got it back it still does it. It is creaking in the drivers seat only now. In the upper back area. It is still in warranty. Has anybody else had this problem? I am wondering if they will replace the seats next?
