I have a 97 960 wagon which I bought a few months ago. When I start the car I hear a loud whine that changes pitch when I turn the wheel. As the Car revs up I does drop in volume and I do feel a slight resistance when I drive almost like the steering is in a groove.
I have fluid and it looks somewhat frothy. Is this a powersteering pump issue or is it something worse like a rack? Thanks

You should see if it has had the updated loop installed.

You can tell by looking under the car by the oil filter. See if there is a hose that runs in a loop then goes to the steering rack.

 

I have A similar problem on my "1990 760 Turbo" it makes a sound almost like chewbacca haha. If you know what it could be that would be nice.

 

I'm still not sure what the noise is. Sometimes it does go away, but then comes back while idling at a light. Not really a Chewy grind but more of a medium toned whine that you can feel throughout the whole car. I'm have almost given up and am now waiting until it all breaks to diagnose it unless I figure it out before hand.
