adjust steering

[My3Sons!]

I can't seem to find anything on how to adjust steering, mainly because I can't seem to figure out how to search for what I'm after. Simply put, my Jimmy will turn MUCH more to the right, than the left. Basically, full turn to the right and wheels are where you would expect them, giving you a very tight turn. However full turn to the left and it's about half as tight a turn. Not sure it's related, or just another problem I need to fix, I have massive play in steering in general, almost dangerously so, but since I almost exclusively drive 30mph or lower I've just kind of dealt with it. How is this remedied, and are there different procedures to address each issue, or are they related? Thanks in advance.
