Not sure if it would apply, but Nissan TSB NTB06-072a of 04/18/2007 Drive Belt Noise (applicable to 2005-2007 Frontiers with the VQ-40) notes that on some builds, the power steering pump isn't properly aligned. The TSB offers photos to check and presents a fix if the problem is present.
This is probably not the cause of your noise, as you've replaced the belt and that would fix it temporarily.
My '06 has this problem. I tried to work the TSB (and it's a pain), but couldn't get my power steering pump to free up so that I could straighten it. The hour was late, so I threw in the towel and bolted everything up as it was. I'll try it again someday.
