spinning sound when car accelerates more than 45 kmh

[shipwreck]

i am having this issue for the last couple of weeks. as soon as the car reaches 45 kmh and above i get a spinning sound from the engine. feels like coming from the left rear, but can't be sure. The engine was smooth only a couple of weeks ago. then it started when the car reached 90 kmh. & recently it is starting when the car reaches 45 kmh & above.

any idea? i'll be taking it to servicing soon.

Maybe it just need to be service
