I have a Wagon R 2012 model VXI. There is metal noise coming from the front wheel. I change the bush kit, the suspension, the steering box, the lower arm but still the sound prevails. It happens when the road is uneven. Like going over rumblers or similar type of roads where in the tyre bubbles a bit. On smooth surface there is no sound. Can anyone suggest on the issue and how it can be rectified.
