2007 Chevrolet Trailblazer Question: Whining Noise when RPM's go up

My truck makes a whinning siund when the RPM's go up. It has been suggested that the power steering fluid may be low...? I've just reache dthe 1000,000 mile mark and did have the oil changed and fluids derviced last week. They said the other fluids were fine, but they also did not reccommend any of the other servicing that your site reccomends for specific mileage marks. Ideas? Thank you, Tammy Davis -
