POWER STEERING PUMP
 

Does anyone have any info on how hard it is to replace the power steering pump. Or if you know of any websites that offer repair info. It's for a 2004 limited 5.7L. I am getting a steady high pitch noise that increases in volume when the accelerator is pressed. At first I thought it was coming from the alternator but everyone i have talked to says check the pump. I checked the fluid and thats full. I am trying to avoid high repair cost from dealership. Thanks
