I have a 99 Taurus LX with the 3.0L engine. It only has 28K miles on it. I get this squeaking sound when I turn the steering wheel. The noise happens in both cold and warm weather. It does not make the sound when at idle or going straight on the road. I know Fords have a lot of power steering whine (I had two 5.0 Mustangs that both whined), but the Taurus pump seems fine. I tried greasing up where the steering shaft goes into the rubber boot in the firewall (near the gas and brake pedals), but it did not help much. The sound seems to be coming from around this area. Any help would be much appreciated. Thanks.
