kovz has 2 very good places to look. the upper ball joint binding and the lca hitting the frame.
the easiest thing to do is put the front wheels on some 4x4s or something where you can let the jack down and simulate laying out without removing the jack entirely, unbolt the upper balljoint and try to set the truck down. if it looks like it will lay out, you need to do what kovz said and pie cut the uca. theres a how to in the tech section. . but by doing that, you just take the uca out of the equation so its easy to see if the upper balljoint is binding up. i bet this is what it is
