squeeking sound from under truck while moving

So while in the sonic drive through today I noticed a weird squeeking sound comming from under my truck. it only does it while moving and gets faster as my speed increases. I thought it might be my driveshaft but I have no idea.

any thoughts?

 

Gotta get under there & check it out. I had a simular noise it ended up being a heat shield rubbing the drive shaft, must of got bent back in the middle of the massive rain storm we had not too long ago. I would get a creaper, beer and look around with a flash light. Let us know

 

Carrier bearing?

 

U Joints if it gets louder/ more frequent as you increase your speed.

 

what would that mean? greased? tightend?

 

i have an appointment with the dealership on tues. so they can take care of whatever it is

 

Pilot bearing?
