I am confused as to what your question actually is.
Your procedure sounds fine to me, but do you have the pullers to get the old parts separated? It took a lot of force to get them apart when I replaced the steering box on my SL. And they didn't come apart gently - as I turned the puller with a large wrench, there was a loud bang and the tie rod "jumped" out. So make sure your hands and other body parts are clear.
