Springs are easy but...
You will likely have to pull the machine out. If it is from 2004, then it is a Point Voyager, Tall Tub machine. Can you provide a model number please so we can be sure? The door had the stop where you leave it "option" and had some wheels and cords to make it work.
It is a relatively easy job to replace them but like I said, you will have to pull it out.
Then replace each side one at a time so you can use the other as a guide and you should be home free. If I remember correctly, the kit is for both sides, but we can check once we have a model number.
