Noise While Driving

[sothunter]

I have a 2005 Ford Ranger xlt 4x4 4.0 Litre v6. Recently i began hearing a sound coming from the Front of the Truck. It Sounds like a Rur rur sound. its very noticable at speeds around 25 mph but is there all the time. In and out of four wheel drive. No sound at full Stop. I thouht it might be tires but the sound is the same on different pavement surfaces.I suspect the wheel bearings but when I swerve back and forth the sound doesnt change. any help would be greatly Appreciated.

Your 2005 4x4 has the front end gears and driveshaft running around and around at all times.. I'd be looking at the U-joints first.
