Whenever I approach 38MPH and up, I always hear this low whistling, turning noise. But, if I let off the gas pedal completely, the noise goes away. Could this be my axles going out? My axles seem to make a lurching movement at certain speeds also. Would you say it's a good time to buy a replacement?

Do you hear clicking when you turn? Are you sure the sound is coming from the driveaxle(s)? Have you inspected the rubber boots around the CV joints for cracking/splitting?

Sometimes a bad wheel bearing can make the sounds you describe. Did your alignment go out all of a sudden? A sticking caliper could also cause similar problems.

Is the noise related to 1)engine speed or 2) speed? Does it make the noise at idle and moving the pedal changes the noise. Or is it related to how fast you are going. Noy enough info.

Sometimes I hear clicking in a sharp turn, sometimes I don't. I havent heard it lately. Rubber boots are okay. We replaced the wheel bearings...3-6 years back?

marc780, the noise is related to speed, as I do not hear it when idling.

Have a trans guy give a listen. Could be torque converter noise.

Check the differential fluid level.
If noise is louder when windows are open it is generated in the power train.If the noise is heard with windows closed but disappears when you rolled windows down, the noise is road/wind/tire related. If noise changes with road surface - this is tire noise.The torque converter noise is not common on Camrys. Such noise is loudest at take-off and should sease above 50 mph, when converter is locking up.
Drive the car at 38mph at 2nd, D and o/d. If it still present at 38 mph, suspect above mentioned components.
Warped brake rotor / separated brake pads produce pulsating howl at float condition, and disappear when brakes applied.

What could cause that lurching then?

This is true. It happened to me when my differential was low on fluid.
