Hi Guys, I have a 96 Disco, with 80K. The Steering is getting tighter and after starting the there is a growling noise, so I asked the dealer to check it out, and they told me the pump needs to be replaced. First of all is this correct, and what else should I replace,i.e., any lines., etc. What should be the cost? The pump alone is around $400, and $600 at dealer. Also I would appreciate any directions if you guys have some info. Thanks AL | ||

Hi Al, If you can change your serp belt, then very easy job. I bought a brand new pump from DAP-Inc for $299. Took all of a couple hours to drain, remove, replace and refill. Got new hose clamps, but left old hoses in place. Make sure you can remove your viscous fan as well. I did mine with the fan still on, and would have been so much easier to do with it off. Remove the fan before you unbolt or do anything (including removing the belt). | ||

Al, from my range rover experience, it seems to be true. On a 96 Disco, p/s pump is much more accessible than on 3.9, and the job doesn't seem to be any difficult. | ||

Contact Meredian Auto Parts in San Diego -- I got a rebuilt pump from them for about half the dealer price a couple of years ago and have had no problems since. If their pumps are as good as their rebuilt steering boxes, it should be quite an improvement over the factory unit. ---Norm | ||

I am having power steering problems as well but I cannot decide if the pump is bad or the steering box is bad. Help would be great. Here is some other info. The fluid (Dextron III) foams when fluid is added while the engine is running. Does this seem to imply that the pump is work but the box is bad? Thanks in advance. Lee | ||

Lee, you might want to try to purge the air form the system to see if that solves the foaming problem. There is a fitting on the top of the steering box. With the engine running, slowly loosen the fitting until fluid runs out in a smooth stream with no bubbles. | ||

Thanks Mike I will try that. My truck leaks about 8 ozs per day of the stuff so I am often looking at it. Any ideas on my other questions about whether it is the pump or the box that is bad? Or any ideas of troubleshooting to find out myself? Thanks, Lee | ||

Lee: You may also be entraining air in the fluid through the leak. You may think it is onlyleaking out, but air is leaking in. Mine did the same thing, it looked like a Strawberry frappe. A few hose clamps and it's fine now. Still leaks from the bottom of the box, but I can live with that, buy ATF by the five-gallon bucket and all is good. Paul | ||

Try to isolate the leak first. Degrease the whole system (hoses, resevoir, and steering box). Start the engine and try to look for a leak. There's a good chance that severe leaks like yours are from the lines going in & out of the resevoir. Like Paul said a few hose clamps might be all you need. Mine leaks from the bottom of the box as well, but it is only enough to amount to drops not ounces. I just added some Lucas power steering stop leak. Hopefully it will help seal up the box. | ||

You might try something as simple as flushing the system with clean new fluid and putting some 'trans-magic' seal conditioner in the flush mix to help the internal seals swell back to life. Sounds like they have shrunk to the point of leaking or a hose is loose, 8 oz is alot of PS fluid. | ||

Thanks guys for the info, I will check it out at DAP and Meredian. Any info on a link for exact steps??? Thanks! AL | ||

Paul and Mike, Where are the typical spots for the hose clamps and would you not recomend Lucas ATF sealer versus Lucas power steering sealer since it is ATF fluid? Thanks for the information, Lee | ||

Just had a similar problem with my '98 D1. It turns out that there was a slow leak (or weep) from the hose / pump connection. The little stainless steel crimp clamp has loosened somehow. I just cut it off, and put on a new stainless steel hose clamp. Wiped the fluid off all of the parts and it works. | ||

Lee: From what I have observed on a number of Rovers, the most common places for these systems to leak are at all of the hose clamped connections: Both of them at the reservoir, the supply line to the pump, and the return line from box to reservoir. I also had a begining failure of the high pressure line from pump to box and had a new line made. | ||

Paul, a bit of info for you - if you haven't come across it already. some of the Saginaw pumps used the remote reservoir - meaning that if one ever came out with mounting brackets, the potential market could expand onto 3.9s as well... peter | ||

Peter: If the weather ever improves, you'll see the Saginaw conversion happen! Now that my box is leaking as badly as the pump/lines used to, there is greater emphasis for me to hurry up and get the box done too. I also have a request to put a Saginaw box on a buddy's 110. No end in sight for these projects. Oh, yeah, I have run into a stumbling block-I cannot get the flange off the ZF pump Blue sent to me. Any suggestions? I have tried a wheel puller and am ready to make a bracket so I can put it in the press, but I'm afraid I'll break something doing it this way. I need the flange for the conversion. I've used a big cheater bar and a big vise with the wheel puller, but can't get the damned thing off for the life of me! | ||

I am not sure that ATF was used in my 99 Disco (may have been replaced). How do you drain it and refil with the right fluid? Dealer said they used an amber colored fluid and to just add ATF...I'm not sure I am ready for any of those consequences when I can see the leak is the hose! | ||
| Paul T. Schram (Paulschram) Senior Member Username: Paulschram Post Number: 1121 Registered: 02-2002 |
Nick: One could use a turkey baster to remove what is in the reservoir and suck out as much as oyu can, replace with ATF, wait a week, repeat, wait, repeat. Eventually, you will have removed a volume equal to several times the volume of the system. Or, you could hokk a hose to the bleeder, open the bleeder and as it is pumped out, pour virgin ATF into the reservoir. Given more time, I could get more creative... Peace, Paul | ||

Being a new Disco owner, I am grateful for this site and the advice. Thanks. I was thinking about removing the return hose and draining the reservoir into that...but I know that could cause me a major cleanup. Turkey baster sounds good! | ||

Nick: In industrial chemistry, flushing a system with three times the volume of the system is considered to be a sufficient flushing to remove traces of contaminants. When I worked in the electric utility field, we did a similar process to remove PCB-laden oil from transformers, etc. As we couldn't very well darken an entire city, we pulled a vacuum on top, pumped in clean oil from the bottom and overflowed out the old stuff. Worked well then and works fine with our trucks. To some extent, you are doing the same thing when you swap out your old brake fluid. Glad we/I could help. Peace, Paul |
