I have a Grinding noise from Front of Engine 4.3V6

I have a Grinding noise coming from the front of Engine. I thought initially it was Belt tensioner Replaced still have noise, SO I noticed the Water pump had some play so Replace it. Still have noise. so I notice grease on the idler pulley so I replace it. Totalling about $75 I am ok with that. But I still have the noise. My next guess is Power steering but Im not having a loss in steering I thought I saw a small leak but could not pin point and have fluid in resevior. When I hit the belt with a little water, WD40, the Noise goes away. Any advice
