    Well, a rear end can whine a lot. Of course if you have a NP203, the front end could do it too, and you would be hearing it from the front. I wouldn't narrow it down to the torque converter yet, could be anything in your drivetrain.

    this noise came out of no where, its more of a noise now then when i first started hearing it.

    driving down the hwy it starts around 30 mph, and gets louder as i go faster.

    but when i let off the gas the noise kinda stops?

    I would vote for a rear end. I say your pinion bearings blew apart and the pinion is being pulled into the ring gear teeth producing the whining noise. My 14BFF had bad pinion bearings and had systoms EXACTLY like you described above... the whining would get louder the faster I went and would quiet down when off the gas because the pinion would then push it self back out of the teeth, producing less noise. It was about a hundred bones to have the local rear end shop pop in new bearings and a seal. The old bearings came out in pieces.

    I *believe* converter noise is typically when in park/neutral, not when there is a load on it.

    silent but deadly....

    Some torque coverters can fail and make no noise,like when the stator goes bad--I have seen them blue from overheating,but they made no strange noises,it was more evident by the way the vehicle drove,felt like it was stuck in a higher gear..I have also heard some that sounded like something hitting a fan blade...I agree it sounds more like a rear axle noise,maybe put it on a jack or lift,and use a stethascope to listen to the suspected parts for noises....:crazy:

    Power steering pumps and an automatic tranny with a plugged up filter can whine like a siren too,but they will do it all the time while its running,not just while the truck is moving...:crazy:
