Rear End Whistling Noise?

[Mckenzie]

I keep hearing an annoying whistly/ screech noise coming from the rear of my truck near the tire on the drivers side. I can only hear it while accelerating and it stops right around the 25-27 MPH mark. I can clearly hear it in the cab and it is as annoying as hell. What could it be? Im running pretty mild tires, they are Geolander 265's.

Could be rear universal joints, bad rear brake9s0 or wheel bearing. No way to tell just from the noise, need to look into more and know what you are looking for.
