I've had my local branch of organized crime (aka "the dealer") replace the steering box on my '94 Disco twice, the last time was about 4 months ago and it's leaking again. It's definitely the box - pump and hoses are fine and dry.
It's a stock vehicle, no lift, stock tires and this last box hasn't seen any serious off-roading.
Am I just getting bad boxes off the shelf or should I be looking at something else - what would make the steering box seals go?
Any advice would be appreciated.

a bad bypass valve in the pump would do them in
change the steering gear..poof the go again
till you get the pressure down they would keep going to I'd guess
is your steering really light??? |

Are you paying your dealer for this? If yes, then that may be the answer to your question. If no, then you're probably just getting bad boxes off the shelf - you're getting a bad example of a bad product. There are suppliers other than your dealer who supply remanufactured boxes that don't leak. I'm sure others will chime in here with some names.... |

The bypass valve in the pump doesn't sound like anything that can be replaced by itself, if it is that valve will that require a new pump?
How can I check the pressure in the system? My steering is remarkably light for a vehicle of its size. |

I'm beginning to think Rover purpose designs flaws and weakness in their equipment (i.e.: steering boxes, manual transmissions, overheated aluminum motors, electrical gremlins, etc.) in order to generate revenue for themselves and their stealerships. There's no excuse for using an steering box with chronic hemophilia all these years. Did they ever fix this problem on the Disco IIs?
Forget about getting another stock unit. Get a rebuilt box from Meridian Auto Parts in San Diego -- they've managed to rectify the built in flaws on the factory unit and give a long warranty (lifetime?) at a reasonable price.

The bypass valve can be pulled out and cleaned, but it is a pain in the ass to do as you must remove the pump which isn't that bad if you know how it goes together. In spite of my having far too many manuals on this vehicle, the pictures don't show those last two bolts.
Now for the bad part. LR doesn't want you doing anything with these boxes and the suppliers to ZF don't want to sell parts to anyone but ZF!
The good part... The parts look amazingly similar to Saginaw parts... Now that I have R&D stock (both Sag and ZF), in the unlikely event I get some free time (ANOTHER dead car was towed into the driveway last night for an engine) I will try to swap some of the internals to see what happens. The mechanics here in the plant swear that the ZF pump is identical to the hydraulic pumps in the injection molding machines here in the plant! I suspect that in an emergency, Saginaw parts might just work in a ZF-at least those that have similar physical configurations.
Brain fart! Jim: Disassemble your pump and check that the output valving is working... Pull the output fitting, there is a mechanism back in there that is prone to clogging or sticking. Yours might just be sticking and allowing the pressure to elevate. The output hose requires a 5/8" wrench and the fitting is 1". Don't over tighten either one when reassembling. WHATEVER YOU DO, DO NOT REMOVE the bolts holding the pump together (front/rear cover)-the bearings are a real pain to put back together right!
Let me know if you need to be walked through removal of the pump from the engine.
