Excessive Road Noise & Resistance

I've been having this on-going problem for months, but it's recently seemed to get A LOT worse - I'm hoping someone can help me.

When driving I’m getting this "wooing" sound that’s in a "whirling" type of sound. It's definitely speed-dependent - so the sound goes with the speed of the car.

But recently when I go above 60mph, it gets A LOT worse. I was driving on the turnpike and at 60 it gets louder, 70 I can actually start to "feel" the speed (if that makes any sense) and when I let go of the gas, I can actually feel the Jeep slowing down.

I checked the RPMs and they were just below 2k - so I know the OD was kicked in - but you would never know it from how it felt.

I tried doing 80, just to see what it would do, and it honestly scared me to keep it at that speed. The noise was louder, the Jeep "felt" like it was going 100+mph, and as soon as I let go of the gas, I could defiantly feel it slowing down - it loses speed quickly. I also felt like I had to really keep with the gas to get it at 80 (if I didn't it went below 70 in seconds) - as if it was really struggling - it was never that way before.

I don't really notice a difference in the acceleration or anything else, just crusing. My girlfriend even made a comment about it tonight, and she usually doesn't notice things like that.

I drove it for 120 miles of turnpike today and the temp and oil pressure gauges both looked normal the whole time.

Can anyone help me with this? Or give me a direction to work from?

My guess would be bearings, axle, wheels, something in there.

How many miles on the vehicle? I'd say probably ready for unit bearings and shafts too. Usually the shafts will click, snap, or pop when they're bad, especially when putting it in revers. Much less labor to do both at the same time.

34,500 miles - and I don't recall ever hearing any snaping or poping sound - the noise is only while normal driving. I took it doing some light wheeling a couple weeks ago and it didnt make any weird noises.
