I have a 1984 gmc 1 ton pick up. It needs an Idler arm and a pitman arm. The pitman arm looks like it needs a puller to get it out of the power steering box, but the Idler arm looks like I can do it with a pickle fork. Anyway, if I do manage to get it off, I presume the nut that comes with it will hopefully press it in, then the cotter pin and I'm done?
