Issue Fixed!
Okay kids.. I need someone who knows a hell of a lot more about trucks than me.
Recently, I've developed a whining. I'm assuming it's the drivetrain, since it doesn't increase with engine noise, only with the actual speed.
Problem is, I'm having trouble isolating where it's coming from. On one hand, it sounds like it's coming from the rear end (which I just had a leak fixed with), but on the other it sounds like it's coming closer to me in the cab, which leads me to believe it may be transmission.
The third possibility could be the transfer case, but I'm not sure.
So, I'm looking for theories as to what it might be. Cash is excruciatingly tight at the moment, and I can't afford to be without a vehicle either.
Thoughts?
Thanks!

I would, but I'm going to take it back to the shop first.. The more I've been talking it over with a coupel of other people, the more I'm suspecting it's the rear.. Especially after hearing TReff's suggestion too.. And, since they just worked on it, lets see if they'll fix it for nothing..

Thats why i posted what i did...
maybe the shims were moved around or something...

Looks like explodr4.0 (and any others who might have suggested it) is right. Looks like it's the gears. So, it's in the shop getting fixed. Hopefully they'll get it done quickly so I won't need this rental for more than a couple of days.
And, sadly, this definitely means no more wheeling for me. Not until I'm more financially stabile. I know for a fact that the abuse I put it through has had something to do with it. Like, the abuse I put it through in Centralia turning the truck into a snow plow. And the countless other times I've beat the hell out of it wheeling.
I'll let you guys know for sure what exactly it was when I find out, but they definitely confirmed it's something in the rear-end.

Skot, I forgot what year your truck is, but if you solved the problem by re-filling the diff oil, disregard this.
Some Mid-00+ trucks have had problems with half-shaft excluder seals (dust seals) going bad and causing some whining, more commonly in colder weather. The whining can be noticed more prevalently from speeds from 10mph to 45mph, then wind noise generally mutes the sound. There is a TSB out on this, and if you have a remaining warranty it should be fixed for free.

Sorry it has taken me so long to get back to this.
Bob, the first time for the rear-end work, it was just fixing a leak. They shouldn't have messed with anything, since the leak was only on the diff cover anyway.
This time, it was a completely different ballgame. Here's right from the paperwork:
Needless to say, it wasn't cheap, but I have no one to blame but myself for it all.

Is the noise gone now? My truck started doing something similar recently. It howls when coasting at some speeds between 35 MPH and 55 MPH. Hitting the gas makes it go away and it is most noticeable at just under 55 MPH. Above 55, below 35 and some in between it is quiet. I have heard that it could just be a chipped gear. The dealer filled the diff up last and they put 75W-140 synthetic in it. It seemed a little low when I got it back, so I topped it off with more, but that didn't change the noise. For the time being I am just leaving it alone since I can't afford new gears anyway. I am a little hard on the truck, but not abusive. The previous owners were worse than I am.
BTW - there is no play in the pinion on my truck and I don't think anything back there aside from the fluid has ever been messed with.
