Old steering box was causing a wobble, so I bought a used replacement. That was January (!) and I've just got round to fitting the replacement as mine had progressed from wobble to seal failure.

The replacement has obviously been sitting for a while but even so I was more than disappointed to discover, after spending two nights replacing PAS pump and box, that it has a massive leak. I think it's coming from the output shaft seal but am not 100%. PAS goes from full to empty in about two miles - it's completely unusable.

Deterioration in storage? Do they do that?
 
If the seals rubber it could degrade couldn't it? Can you rebuild the box with a kit? Not much help I don't know anything really but that's probably first thing I'd look at rebuild kits. Good luck!

You can probably get a recon box. Shop around, not all recon stuff is created equal.
 
Sigh.
Saves me the hassle of trying to fit a seal kit to a bad box, at least.
I've got another box that has been on the project truck which won't be running for a while; I'll fit that tomorrow and then source another box to replace it.
 
Swapped another box onto it overnight as I had it available. Leak is gone. Unfortunately, I'm not getting a lot of assistance at low speeds. I didn't get this behaviour with the previous box, so I'm thinking it shouldn't be the pump. Fluid level seems stable and I've bled it from the steering box itself.

Try running the injun, and slowly winding the wheel full lock to full lock a few times, then check reservoir again.
