1 5/16 wrench. Just did one last week. Be prepared to fight the Pitman arm off of the steering box shaft. A pickle-fork bit and an air hammer make it a piece of cake. Some guys unbolt the steering box from the frame to wiggle the steering box into a position where they can get a Pitman arm puller on it. Either way you will need some pretty specialized tools.

You need an approximately 3/8" Allen wrench. Preferably one that is driven by an impact driver.
