Loud squeal when turning?

[pavel]

He has already changed the serp belt (see post #11).

Williampdx: some years ago there was a screaching sound coming from our Disco and a new belt cured it. Did you get a LR (7 groove) belt or a cheaper aftermarket 6 groove belt?

There is a way to check that the tensioner is putting enough tension on the belt but IT IS VERY DANGEROUS!! What you do is get an old broom handle and push against the tensioner increasing the pressure on the belt WHILE THE ENGINE IS RUNNING AND SOMEONE IS TURNING THE STEERING WHEEL.....of course, if the belt grabs the broom handle it will cause a disaster so I don't recommend you do this as you could end up with a broom up your nose or through the radiator. Disregard this stupid suggestion!

Yeah I agree usually squeals from the steering are result of a slipping belt, if you go off roading thru water they often slip for a while after. The pumps can make a heck of a noise also, but usually not a high pitched squeal, more a groaning/grinding complaining sort of sound.

Are you sure it's the steering making the noise, and not the fan/alternator belt. The extra strain of the pwersteering pump running could cause something else to make a noise.

Without hearing it, its hard to give anymore info.

Does it make the sound only when turing the steering wheel, or will it do it if you just wind some lock on and leave it sitting there? If it squeals while the steering wheel is not moving then it can't be part of the steering mechanism (bushes, rods, etc.) and must there for be the pump, belt or some other component under the bonnet which rotates while the vehicle is stationary.

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Okay - I finally determined (correctly) that is was the PS pump going out. It was moaning at all times. I bought a used pump online for my vehicle and just installed it according to the Land Rover Mechanics Guide that I got about a month ago in .pdf. That was a pretty easy task. The next step after installing this is to flush the system by unscrewing the valve screw while it is idleing and letting the ps fluid start to come out. The problem is that after waiting at least 5 minutes, no fluid came through at all. Obviously, my problem now is that the new power steering pump does not work at all. So, I screwed the bleed screw back in and drove the car for the day hoping the pump would start working. It didn't. Of course the moaning problem is solved!!!
My question to everyone out there is this: Is it possible that I didn't bleed it properly, and that if I do the pump will begin functioning properly? Or that it will take a while for it to get through the system because the Lucas fluid that is in there is very thick? Or is it more likely I received a bad pump? I have a feeling it is not the pump because a bad pump would at least make some noises and groan a bit. The seller tested this and said it worked! Also, would it be a bad idea to drive with the valve screw undone to help bleed this through?

Any help, ideas, or suggestions would be much appreciated!!!!!!!!!!!!

check to make sure the hoses aren't wore out. I had similar problem, I had someone turn the wheel while I watched under the hood, and the hose was sucking itself shut under load. I hope this helps!!
