A few months ago I was driving on a curvy backroad with the windows down. As I turned the wheel left or right to navigate the various bends and curves I noticed a metallic rubbing sound when the wheel was turned about 1/2 to 3/4 full lock. I went home and topped up the power steering fluid which was quite low. I then that the leak was coming from the bigger house that comes out of the fluid resevoir and then goes into the pump. The fluid was seeping out where the resevoir meets the hose. I have kept up on the fluid level and it only drops very slightly every couple of weeks.

Now when I make tight turns while travelling slow, like navigating through a small parking lot I hear the metallic rubbing sound again... Now for the really odd part... I notice that on colder days that I do not hear the noise, maybe just by conicidence though. The fluid level is fine. Could this be trapped air in the system? I want to flush the entire power steering system and bleed it of any remaining air, but I need to fix the leaky hose first.

The hose in question is #5 in this picture, but Eeuroparts don't seem to sell it or list it. Can anyone help me find a cheap source for it?

They don't seem to list the part on the website. I've seen hoses listed on other websites but I'm not quite sure which hose it is. Is #5 the pressure hose or the return hose? I'm really confused here.

Here's a link to the website that lists the hoses: TheSaabSite

Could it be possible that a small hole in a hose could be introducing the air into the steering system, thus creating the noise I am hearing. Anybody make sense of this?

Also forgot to mention that my car is a 1991 9000i 2.3l manual

Jesse, the haynes manual states that when draining the power steering fluid
"clean the area around the connection point for the fluid return hose(this is the smaller diameter uppermost one)" so according to this the larger pipe(pipe 5)is the supply pipe from reservoir to pump.HTH .Col.

Sgould,

You mean the wheel bearing right? I will have to check that out... I've suspected that one or maybe both of the front wheel bearings have gone south. Could the disc rubbing against the pad cause premature wear on my front brakes?

$88 isn't too bad for that hose I guess. I just hope it won't be too hard to replace

It seems like you have a very similar problem to me, ive just changed the front left wheel bearing(refer to the link sgould has posted) and now i am noticing that when i turn right, i get a metallic rubbing sound, which i guess is because my right wheel bearing needs changing. Also my car is a 1991 9000xs 2.0injection, so our cars are pretty similar, and so might have a similar fault.
Just got to find some time to fix it
Also as to ure question about premature wear, it seems on my car that the disc is being worn just inside of where the brake pad usually touches, so i dont believe its actually wearing down the proper braking surface of the disc and so isnt really causing any major wear, and i guess eventually the inside surface will be grinded down to the point where i wont hear it rub(sorry if this makes little sense, im pretty new to cars)
Anyways good luck and if it is the wheel bearing its a pretty easy job if you have the right tools

I would go with the hub-nut suggestion. I noticed a similar , intermitant, noise on my last 9000 and it turned out to be the hub nut.
It's a large nut in the very centre of the wheel which holds on the hub ( not surprisingly)
Sound was like a metallic scraping sound. V. unpleasant sounding but easy to fix. THe guy in the tyre fitting place who sorted it said he had seen it before on 9000s and recommended applying some "threadlock" to the nut prior to re-tightening.
Also check your wheel nuts , this can make a similar sound. I once drove all the way to a Saab specialist to have this "fault" diagnosed. Boy , did I feel stupid that day.
