I think I may have an idea what it is but lets see what you all think, I have a 2004 1500 Ram 5.7 hemi with 60K miles. The problem is a whining noise in engine compartment that varies with RPM change. Thinking a possible alternator going bad? Have had a P/s leak in the past but never let it run out of fluid. Also I can crank the wheels and hear the pump working which is a different noise. Any other ideas?

Well, decided to remove the belt again and hand spin all the accessories to no avail. Which kinda ruled out the tensioner and idler pulleys. Put belt back on and started motor and with a long extension, very carefully "felt out" the alt, a/c comp, and p/s pump. Got the most noise out of the alternator. So after getting a remain alt from the local parts house and few minuets of install time the noise is gone... Just glad it didn't seize while away from home...

That would have been my guess too, and when your P/S finely takes a dump you'll know it, even with full fluids you'll hear a wine that varies in rpm when you turn the wheel, it took a year and a half for mine to finely kick the bucket.
