whistling sound coming from rear of car

Is this loud enough to get a recording of it? Do you hear it when accelerating or decelerating? When you reach a certain speed?

Does it sound like an air leak in a window or a rotational noise?

Here is a guide that helps with whistle noises. Let us know about this and we can go from there. Thanks

It is a rotational noise as soon as I start driving I hear it.

Okay. Jack up the rear of the vehicle on that side and just spin the wheel by hand and see if you can hear it. This is most likely a bearing or something dragging so hopefully you can hear it just by spinning by hand so we can narrow it down. Keep me posted on what you find. Thanks

Thanks.

You are welcome. Please let us know what you find and we can take it further if you need more help.

Thanks, I will.
