I've recently noticed a 'groaning' noise (on my 1989 560SEL only 45k) that seems to be coming from the steering wheel when I turn it, especially at lower speeds, i.e.. like pulling into the driveway. I thought it would be a lack of steering fluid, but the wheel doesn't seem to be "heavier" just makes the noise, regardless when I looked under the hood the fluid reservoir located close to the wall separating the engine compartment from the cab looked full (i.e. filled to the MAX mark) but another fluid reservoir close to the front on the car (marked HYDRAULIC) is about half way down. Question is Could the low level of fluid be responsible for the noise? Would the wheel not also be heavy if it was a lack of fluid? What fluid is the right type to put in? Any other thoughts come to mind before I take the car in for the MB techs to look at it?
