It continues from 2500 but as you go faster and everything gets noisier it is not as noticeable and changes to a higher pitch. It is real bad from 2100-2500. I wold think it is a wheel bearing, except that when you engega the clutch while running down the road at 70mph, the sound disappears completely. If it was a wheel bearing, I would think it would keep singing. Any ideas?

Thanx!

My guess is the Ring and Pinion. Does the pitch change when in accel or decel at those RPM's and gear selection you mention?
A loose wheel bearing will also generate a groaning kind of noise when the brakes are applied with moderate pressure at highway speeds.
