Land Rover Repair: 99 Discovery 2 Steering box leak, steering box, discovery 2

Question
Hi Ive go ta PS fluid leak - not from the bottom seal as usual - but from around the adjuster nut on the top of the steering box - can this seal be replaced ? - access is tight to get to the top - maybe remove box to do it ?
Thanks in Advance for any advice or tips

Answer
I have never seen a steering box on a Disco 2 leaking from the top.  It is more likely to be a steering hose that is above it leaking onto the steering box.  The feed pipe from the reservoir to the pump is right above the steering box.  It is probably a leak from this.  If the steering box is leaking from around the adjuster nut, you probably need a new steering box.
