Have a Dodge Ram 2500 V10 8L . When I place it in drive there is extremely loud buzz.. almost sounds like there is a weed eater wide open in the front underside of truck. The noise does not accelerate when engine accelerates nor does it make a sound when the breaks are applied... but any amount ofgas and the sound begins. Doesn’t make the noise in park, neutral, or reverse. Hard to pinpoint cause of noise because only happens when truck is moving in forward.

here you go. here is a video i recorded this morning
