Guys,

My 97 Disco one is making crazy whinning sounds when I turn as if the power steering fluid is low, but I just had it flushed and refilled about a month ago and I had a leak repaired as well. Could it be that my pump is going bad and that's why it's making that sound? Whenever my fluid was low it would make that noise and be hard to turn in the morning, but it's not hard to turn, but it does make that sound.

Any help would be appreciated big time.

Thanks
RLB
97 Disco

Just because you had it flushed doesn't mean it all hasn't leaked out, check to make sure that you do indeed have PS fluid in it. Also, the factory hose clamps are crap. Remove them and replace them with standard hose clamps at the reservoir and the pump, my PS system looked like a crime scene until I did this on my D1. Top off with any anti leak PS fluid (I like Lucas-available at fine truck stops everywhere)and see what that does for you.

I will let you know how mine turns out. As I pulled into work this morning I heard the whining and squealing so I popped the hood only to see PS fluid pouring from around the pump, hoses and even the resevoir look as if it had backed up and overflowed. I'm not much of a mechanic, so after calling several places here in SW Georgia I found some who will work on it tomorrow. I'm praying for a hose leak, please not the pump!

My PS fluid was leaking all over due to the so called clamps that they put on. Once I replaced them with some real clamps, the leaks have stopped. Good luck on getting that fixed.

Dealer "serviced" my PS system while under warranty. I guess that the actual fluid wasn't covered by warranty, because they left that part out. Pumps don't like to run dry. If your pump has starting sounding like a burning kitty cat, then it's about to give up the fight. Pick up a salvaged PS pump and slap it in there.

Well Raymond hope you have better luck, mechanic told me mine was the PS pump and hoses$$$. It never made any noises till it crapped out yesterday. I love my 97 Disco but after it comes out of the shop it will have to go, I can't afford it. Some day when I can afford one I plan to buy another. LR's are unique and wonderful vehicles.

I am also in the processs of replacing my Power Steering hoses. I have a nice leak happening.

I remembered that awhile back someone mentioned that they purchased some general duty hoses at a local auto parts store.

Does anyone have any recommendation as to what I should look for in new power steering hoses? Part Numbers, claps, etc?

Thanks

FWIW...don't forget to use ATF Dexron III, and not cheap PS fluid

Guys I had mine flushed and had the hose replaced, but when I checked it yesterday the fluid was really low which makes me think there's still a leak somewhere because I had this service done 2 months ago and I don't think the fluid would go down that fast, but if I'm wrong please let me know.

Thanks

Fill it back up again, there may have been air bubbles in the system after replacement of hoses. If its low again after a while then I'd worry.

OMG-you only check the PS level every two months? How long have you owned a Rover? LOL.

Replacement hoses-make sure you use a hose that is compatible with ATF and not just heater hose (yes, I know I suggested this a long time ago and got soundly flamed for it). Gates LOLA+ is a good substitute for the low pressure lines. For the high pressure lines, go to your local hydraulic shop and have them make you new hoses-far cheaper than OEM.

Any good quality worm gear clamp will work fine.

Peace,
Paul

I had the same problem with my rover when the dealer took it in for service. They flushed my PS fluid but forgot to put some new in there. I filled it with ATF Dexron III right when I got home and two days later I had to top it off again. Make sure all your hoses are clamped really good, this stuff leaks out like crazy if your clamps are weak or if they are a bit loose. After second top off I have not had any problems

Look around, and maybe you'll get lucky.
I purchased my hoses for $90.00 and so far no worries. 2 months and still at same fluid level.
I try changing the hoses first and that whining noise should go away.

Hi Guys,

I had the same type of problem with my Disco, Tdi, let me share what happened. I had a leak, not very important, but still worrying. The oil would drop on the parking place when the Disco was parked, but it wouldnt leak like crazy when i would turn the wheels (high pressure hoses under pressure).

It was impossible to see where the leak was coming from, even by looking under the car, and having someone turn the whell, engine running.

I first changed the High pressure hose from the pump to the steering box, the problem got a bit worse, with more leak, and the sound you describe occuring when turning the wheels. So i had to order a new pump and replace it my self.

A friend of mine had another trouble, that was when turning the wheels, the oil would pour out under the engine : he changed the high pressure hose and that was it.

All this bought me to the conclusion that a sound like a loud scream, that worsen (gets louder) when you turn the wheels + a steering that gets harder, shows that there is likely the pumps to replace (pumps are very difficult to repair), and a leak that occurs when turning wheels show that a hose could be leaky.

TO try and help looking where is the problem from, first clean very carefully the engine bay and pump using high pressure hot water (just watch eletrical devices), then start the engine, look if you hear the sound, leaks, and then have someone turn the wheels for you, and check is there is any leak...

Hope this helps.

Krys

$90 for hoses? They would have cost you no more than $20 each at a hydraulics shop and likely have been of better quality. I have BLing BLing stainless braided lines that are priced around $35, including the AN fittings. The low pressure return and supply lines cost about $2.00/foot and the clamps cost next to nothing.

Krys is right about not rebuilding the pumps, although, they aren't much more than a tiny hydraulic pump. The problem I have run into is that the bearing mfgr claims ZF owns the rights to the bearing and won't sell the components. The blueprint I got (don't ask) states clearly that the drawing is the property of ZF and the numbers are even ZF proprietary knowledge. When you open the case, parts end up everywhere and are VERY difficult to reassemble, even if you can find the bearings.

Some day, brackets will be available to retro-fit Saginaw pumps with off-the-shelf parts, we're almost there... Then, onto retro-fitting the Saginaw gearboxes. Got to do somethign with all of this junk I told the wife was for R&D!

Peace,
Paul

My disco left me stranded last nite, I was taking a turn when all of a sudden I couldn turn the damn wheel, luckily I was really close to some empty space and stopped there and waited for some help, turne out one of the pressure hoses had unscrewed itself from the pump so I used a wrench to tighten it and poured some new power sterring fluid in there. I turned the wheel a couple times and made a weird noise, like screaming... I turned it all the way back and forth a couple times and it went away, I assume some air got in there when it dried out and after a while the noise stopped, it still felt a little weird when i steered but after the drive back home its back to normal...

2 things...

First it concerns me that Joel couldnt turn his steering wheel just because of a power steering foul up.. Where you just not able to do so easily, or could you really not turn it.. I dont see what it couldnt be turned but someone correct me on this.


Second..

Paul, hook me up with your source for the bling bling...!!

Actaully yes it felt like I could NOT turn the wheel.. it was that bad.. but it had emptied out COMPLETELY, one of the pressurized hoses came loose... I was able to turn a bit, cause if not I would've crashed....
