If you don't have the skillz to do most of the work on your squarebody yourself, it really doesn't make financial sense to bother buying and owning one. Man, I took a serious screwing at a front end shop because I got too lazy to replace my tie rods and idler arms myself.
I bought the idler arm and the inner and outer tie rod ends, plus the sleeves. That cost $150. This 'service center' removed and replaced them for me. They charged $80 a side for the tie rods, and another $80 for the idler arm. I paid $240 labor for being too lazy to spend 2 hours to do what they did. But my God, $400 to do just part of the front end? Not to mention, they did the alignment, (more $$), but didn't drive the truck after. So I got in it to head home to find there's still serious play in the front end! Got home, shook things around some more, and saw the pitman arm has play,too! But needless to say, I didn't bring it back to those jokers. I'll do it myself, like I should have to begin with.
