Probably find its the right hand wheel bearing, sometimes its difficult to tell without jacking car up and spinning wheel,always best to replace both bearings anyway as one usually follows the other, imo.

Hi Rob,

All these parts replacement were done at the garage, we took the car up the lift tried to run it but there was no sound. All the youtube videos and other online media as well as mechanic suggested it is Left hand bearing as the sound stops when we turn left as there is no /less pressure on the left wheel.

After replacing the bearing when sound still continued the suggestion came as Drive shaft joint may have gone bad as its rubber was broken for some time. We tried checking it and finally did not find anything there and drove the car again after proper greasing the joint and replacing the gear oil. The sound still continued and we finally ended up replacing complete drive shaft.

Along with left hand driveshaft replacement, we opened right CV joint and replaced the rubber and greased it after checking.

Now this sound keeps me amazed why it still continues or where is it coming from.
