Help with a squeak problem

So I have research this problem and have came up with multiple answers. So I really don't want to throw parts at something hopping to fix it. So this site has helped my fix some problems with my truck by researching I thought I would turn to the experts again. My issue is at low speeds from 5 to 20 after that my exhaust is louder so I can hear it. It could still be present. But I get a squeaking noise that seems to go with the rotation of the wheels or driveshaft but goes away once I press the brakes. I was testing it out today. I changed my pads and rotors less than a year ago. Because my rotors are warped and I'm starting to get the same problem again. So I'm wondering if this issue has to do something with the caliper maybe sticking. Any good info will be greatly appreciated.

 

Wheel bearing? The load of the brakes on the hub could be hiding the harmonic "squeek"... What's it do at higher speeds? Any whining?

Other than that... Mine would squeek to hell when my ujoint (the one by the rear diff) was going.. Pressing the brake changed the drive shaft rotation speed... So it went away randomly.... I replaced all 3 with greasable ones I picked up from carquest...

The final possibility would be a pad/rotor issue... That's the only thing left really...

 

Don't hear anything at higher speeds. It's a squeak that goes with a rotation. I can slow down and the squeaking slows or speed up and it gets faster. But it's not always there seem the longer I drive it the sound goes away. Or you tap the breaks at low speed it goes away.

 

Mine did the same thing when my final ujoint was going...

Are you getting any weird vibrations.?. (My rear view was shaking whenever I tapped the gas)

 

I do get a lot of vibration some from warped rotors when stopping taking him back to the parts house this weekend. An others when driving.
