My car started making horrible graoning noises over the weekend whenever I turned the wheel. I checked the power steering fluid and it was low and there were little bubbles in there too. I added some and made an appointment to have it checked. After I added it was fine almost immediately. I then parked it in the snow for a couple of hours to see if I had a leak and sure enough there was pink fluid.
Hopefully it is just a hose or a clamp and not the whole rack. I am in the Detroit area and it has been bitter cold the last couple of weeks which makes me wonder if this had something to do with it.
