My girlfriend has a 2003 Mazda 3. We just went for a road trip from Austin TX to South Padre Island; about 6.5 hours/350 miles. While sitting in the passenger seat, I can hear a sound coming from the front right wheel area. It is a regular sound, meaning it happens once per wheel revolution. It is loudest while turning and from about 15-45 miles/hr. From the drivers seat, a vibration can be felt in the pedals and steering wheel at the same frequency as the sound. The vibration is stronger from the passenger side. From my experience, this would seem to be a tire balancing or wheel alignment problem. She took the car to a tire shop today and they rotated the tires and tested them for balance. They reported the tires all balanced. She has reported that the sound is still in the same location but is slightly more intermittent.

Wat do?

 

That could be the wheel must not fitted correctly. jack the car on top and try to rotate the wheel by your hand.
