Question type: Maintenance & Repair

Is there any way to eliminate the low but chronic noise of the power steering pump on this car?  I have replaced the entire system but the pump still hums a little when driving and is noisy starting up on cold days.  The steering works fine.

Are you sure it's the power steering pump making the noise? I've seen bad bearings in belt tensioners that make noise. If you're sure its the power steering pump, there are many additives that you can purchase. Lucas makes a good product.
