The current agreement is the noise is a howling.

The howling noise comes out of the car hood i.E from inside ghe bonnet, nearer the car tyres, the reason I taught of hub bearing. I changed one side hub-the driver side. Now d noise is still there. Am being told to change the passenger side hub also to see if it will stop. Currently I have done car alignment and wheel balancing, also rotating the tyres stil not ok. The sound is most heared when on higher speed but on slower speeds ot does not make the sound. Also if you rev up the car when stationary, you wont hear the noise also. The noise is like this. Huuuuuuuuuuuuu! Hope this description can help Sir.
