Need help with engine noise

[DenaliDrive]

Our truck recently started to make a noise. I think it sounds like the power steering pump, what do you guys think. I have attached a audio file. Thanks.

You can record a video of the noise and move your phone around the power steering pump area then upload it to youtube and link it here, this website does not host any audio/video files.
