Load whistle nose?
This morning coming home from work all of a sudden a loud whistle noise started wail driving it sounded like it was coming from the back end, it dosent do it wail sitting still only when moving, I revved it a few times and couldn't hear anything and I don't have to be moving fast to hear it. I took a look under the car and couldn't find anything out of place but because of not having the space or time here I'm cant rly dig to deep. anyone have any suggestions?

Sounds like your differential is on its way out. I would also spell check your title when starting future threads. Wasn't quite sure what it was saying til I read your symptoms! Lol.
 if that is truly the case,I would look into beefin it up while your in there. Lots of options. Could be wheel bearings as well.

A few times this winter I noticed a whistle as well, but only when the car was really cold and temps were below 15. Not sure where it was coming from. Definitely noticable from inside the cabin though.

Does the sound get louder and/or higher-pitched as speed increases?
Check for debris on the brake pads/rotors. Double-check and make sure nothing is rubbing against the axles or drive shaft. Jack up the rear, spin the wheels by hand, and see if you can pinpoint the source.

Well I drove it today for about 40miles and couldn't hear anything now, hopefully I just had something on my brake pads. It was wet today tho and dry when I first noticed it so the next dry day I'm gonna try it again and see if everything's still good
