Does it sound like this......hmmmmmmmmmmmmm? Is it a "whiney" sort of hum?
Could be your rear gears, either from worn bearings in the differential, or worn outer wheel bearings putting an improper load on the ring & pinion gears. You really need to know for sure what area the hum is coming from.

 

and if u have a two piece drive line it could be a carrier bearing. is there any vibration?

 

I guess it sounds like, when I'm decelerating one of those old air raid sirens just not neerly as loud haha, but the noise does not intensify if I give it gas or let off, and the noise is comming from the rear end

 

And to answer craby, no thier is no vibration

 

Check the oil level in the rearend. Or better yet, change it if it's never been.

 

Go post the question in another thread like 4th gen, this isn't the place for questions like that.
