Ok, I recently had the power steering hose replaced because it was leaking fluid. When I went to pick it up, as I drove off I noticed a humming sound especially when I turned the wheel. I went back in and he said it still had air in the lines and would go away after a few days. Well it's been about 3 weeks now and its still making that sound. The fluid level is ok and the hose is not leaking. He said he could replace the pump but he could not guarentee that the noise would go away. Steering seems to be fine, he said you turn the wheel all the way to the left and then to the right to get the air out of the lines and that's all that you can do. All I know is that I didn't have that noise in the steering when I brought it in to that shop. I hate to replace the pump if that is not the cause of the noise because it's not cheap. It's a 91 se with 140,000 miles but the car runs great other than this problem. Any thoughts would be appreciated
