I just changed my tyres as I thought they might be the culprit. The thing is, the noise got louder so I decided to have it checked. I had two mechanics from different garages check it and they both confirmed that it's the wheel bearings. I can't wait to get it fixed. I can't listen to music with that annoying sound while driving.
I got my car back and it is now running quietly. The culprit was really worn out wheel bearings. Each front bearing cost me P2,700 so total including labour was P8,400. Whew! I can now listen to my music once again.
