It started out low pitched and has increased in the last two days, When it first started I pulled out the Drive shaft to see if it was coming from there, but the noise was still there. Then I put it on jackstands and pulled up and down on the tire to see if there was anyplay, and I couldn't find any. I am leaning toward the hub bearing but it is a lot of money for a guess , so any input will be helpful.

 

try jaccking it up and spinning the tire by hand if it makes the noise still find were its coming from also check your brakes and differential if the bearings are bad normaly they will shake a little

 

wheel bearings will usually make some sort of roaring sound while the wear indicator on brakes will sometimes make a high pitched squeal so probably take the wheel off and visually check to see if they are worn. I usually check mine (even the drums on the rear occasionally) after any large amount of mileage. I don't do a lot of stopping but I like to know how everything is holding up, especially before a trip. I have had it be as simple as a spring coming loose in the drum and dragging around in there making noise

 

So if there is grooves in my rotors could that be the reason for the noise.

 

Might also be an axle universal joint too.

 

I think I am going to start with this and see if it helps.

 

So after I pulled the front axle shaft, the u joint just kinda flops around so I think I have foound the culprit.

 

Maybe you hit a bird and got it stuck somewhere in your truck

 

I think there is a better chance that it was a flock of birds
