steering box leakage

i have a 95 rio grande wrangler...my pitman arm seal is leaking bad on the steering box ...ive heard there are seals for this but im not sure how to go about it...anybody got any ideas

I hear it's not a tough repair, but I've never done it. Although I did have one vehicle with a leaky seal, and just bought the cheapest power steering fluid I could find (Advance Auto) and kept replacing it. After awhile the leak stopped, so it may have been bad fluid or a hardened seal, or both. But after a month or two of refilling when low, it didn't leak again.
