I just did a steering gear box replacement because the old one blew the bottom seal that connects to the pitman. After reinstalling I got everything back in and flushed my system with no problems and no leaks. Drove it for a day and then the next day I noticed a nice little puddle of mercon V that seamed to be draining off my pitman ... I checked everything and cant seem to find the leak, I remember replacing the high pressure line off the steering pump to the MC around a year and a half ago but it has a lot of wiggle room when I mess with it, could it be that line again?

 

Anything that is loose could be a spot to leak, clean it all off with brake cleaner and start looking for a wet spot

 

I figured it out.. The gear box I recently replaced was defective and whenever I turned the wheel all the way to the right it would shoot fluid out of the head of the box.. Then I replaced MC and boom, truck is back on the road!
