Yup,
@Irun, it was a definite facepalm situation.
I'm planning a trip this weekend, and noticed a puddle of oil on the floor of my garage yesterday. I looked closer (but not close enough), and saw the pitman arm was covered in fluid and that's where it was visibly dripping from. Since I was buried in work, in a hurry, and needed parts in time to repair before Friday, I ordered a Redhead steering gear with expedited shipping before investigating further. Last night, after wrapping up work, I had time to dig deeper. I saw that it's the pump leaking down the return line and dumping fluid on the pitman arm; there's no issue with my box.
