If you suspect a leak, check the fluid level often. Mine leaked at the seal where the steering shaft came out of the steering box. But the kicker is, it would only leak under operating pressure so it did not show up on the shop floor where I park it. I found out when I was moving a trailer on my driveway and noticed drips of red fluid. The reservour was quite low by the time I noticed it. Fortnately, this occured within a month of purchase and the dealer replaced the whole steering box. They actually had one in stock which made me believe they had seen this before.
