I am no mechanic.....here is my problem. When my truck is idling or in neutral I can rev it up and no weird sounds at all. As soon as I put it in drive or reverse I get a rubbing squeaky sounds that increases with the rpm,s. I checked everything under the hood to make sure is tight and nothing rattling or moving. It runs great but the sound is driving me crazy any ideas?

 

Increases with rpm or with road speed?

 

Rpm it quiets down when driving
