Default Steering box rebuild

When I got my disco 2 I found that the ps fluid was leaking badly and the ps pump has been running practically dry. I occasionally get a wired cracking sound from the steering shaft/box. So I'm replacing the pump, but was also thinking about rebuild the steering box. The question I have is whether I should rebuild the one one the car or get a used one (which hopefully wasn't ever running dry) and rebuild that.

Any advice?

Iíve never rebuilt mine. There is a power steering box rebuild kit that can be bought with all the correct o-rings and fittings.

I already have the kit, just wondering whether the old box is ok to rebuild after it's been running on low fluid for who knows how long

Generally speaking, rebuild kits are meant for fixing leaks, not solving mechanical issues, unless the kit comes with internals(it doesnt)

So if you are getting noise, poor action, or other issues from the box with it properly filled, the rebuild likely wont help

The noise I get only happens when the fluid is low. I'm assuming that if the box has been run with low fluid the seals are most likely worn - it's more of preemptive strike. The question is whether running a p/s box with low fluid ruins the mechanical components or are they still ok.

I just went through this with a very loose steering box. Turn the wheel off center a turn and plenty of play. I had same dilemma:

A) used of unknown accident, trauma, usage, condition, run about 200$ or so from a place I could return it to if needed.

B) re-manufactured...not sure what was actually rebuilt in it, but probably not the mechanicals to any significant degree (maybe mix and match?), definitely the seals, paint, etc...400-500$

C) New: best option if cash available (and if you do not want to do the install job again). Price has gone up in last few months. I got mine off ebay from a super nice dealer, original 03-04 part number, in original wood box from England, original fixing bolt, for about 800$ shipped. Had phone number listed and easy to deal with.

Basically, the only two things I really care about are steering and brakes.....closely followed by decent tires..

I actually ended up buying two used ones, so with my original one I have three, so hopefully I will be able to cobble up one decent box. Thank you for advice!

I have a spare ps gearbox for my 2004 D2 that I wanted to rebuild and store as a backup. A new unit cost over $1,000 and a professionally remanufactured unit sold through a parts supplier like DAP Enterprise costs around $800 give or take plus core charge. I did some research and found the guys at powersteering.com. Reached out to them and decided to ship my old unit to them for a professional rebuild, cleaning and painting. They quoted me $480. I will update in 3-4 weeks when I get my unit back.

I bet they just used new seals and painted it.

It took me 3 hours to take apart all 3 boxes - it's really easy. It looks like the bearing race on my original worm gear shaft had worn and got pitted. One of the other boxes had a perfectly fine worm gear shaft so I've used that (it was super rusty and beat up on the outside so I opted to swap parts into my original box, which is in much better shape). It took about an hour and a half total time to replace the seals and put it all back together (while I was waiting for the plastic seals to shrink back I managed to sand blast and paint the casing). Total cost was $80 for the seal kit and $120 for the box that I've use as parts donor (I'm not counting the third box since it's left intact). If anyone needs any pointers, lmk.
