I called the Ford dealer, and they wanted $450 bucks for labor. I called Napa and for the good upper and lowers, it come out to $109 per side (or $218 total) for parts.
If I remember right I had about 120 in each side plus new seals for I think 110 so 350 ish for mine with 4wd.
I did the labor my self with a ball joint remover and some patience it is not at all difficult, A little intimidating taking apatr something new, but easy.
