So I have an old k3500 and it has a lot of slop in the steering. I recently (within the last thousand miles) replaced the idler arm, upper ball joints, upper control arm bushings, and the pitman arm is next (though it doesn't have much play). Naturally, with everything tightened up down there my thoughts turn to the big ugly steering box. Instead of getting a new one I am entertaining the idea of $25 rebuild kits from rockauto for a new learning experience and saving some cash. Anyone done this before? Couldn't be too much going on in there right?
