The replies above are right on. Adjust that flathead screw on the steering gear. I have 125K miles on mine that I bought a few months ago. It did have a bad steering gear - it bound a little going left. I replaced the steering gear and all tie rod ends and ball joints and the vehicle is like new! You can get a steering gear for 35-65 bucks used from the junk yards - they are easy to find because they are trooper steering gears but it sounds like you do not need one.
