Hi Gene,
There are only a few adjustments. First, the steering gear needs to be centered in its travel. You can do that yourself. We've discussed it here many times and we probably need to write up a tech tip about it. Second, the caster angle needs to be checked/verified. Somewhere between 2.5 and 3 degrees positive caster is what you want. If your springs are really old and if they've relaxed, it can affect caster but usually not too much. If you use larger tire diameter on the rear than the front it will reduce caster. A caster setting too low means your truck will steer easier but it will wander more easily too. Third, your toe-in setting is important. It ought to be something like 1/16" toward toe-in if all your front end parts are in good shape (and if they're not, I'd suggest fixing them). Worn out kingpins, tie rod ends and even your drag link can have an effect on your entire front end. Fortunately kingpins and bushings & bearings are available and not too expensive to replace. Also you can get new balls for your control arm and steering arm and that will help snug things. You can even get rebuilding kits for your tie rod ends and drag link, too. Unless you remove your front axle and have it re-bent you cannot adjust your camber. Only caster can be adjusted on a solid axle. Hope this helps.
