Howling sound from the rear when driving

[karolisdi]

Hello,

I have a strange howling sound from the rear of my pre fl E46 when reached 70km/h and above. I attached the video to help you realize the sound. I know it's quite noisy but you can definitely hear high pitched howl noise I guess.

I drove to service and they told me it was rear right wheel bearing and they changed it. However the sound still persists. I wonder what can cause it.

Can somebody help me to figure it out? Thank you.

Could be the other wheel bearing or a differential bearing.
