Is It My Wheel Bearing?

Wheel bearing is one part of a car wheel which is very important for the comfort and safety of the wheels of a vehicle. There are so many problems that occur at this bearing wheel, including:
I started feeling a vibration in my 2008 Hyundai accent while driving at a constant speed. the vibration doesn't get worse or better when i turn the wheel either way. I was told its my front driver's wheel bearing (not by a mechanic) but i just replaced both front wheel bearings less than a year ago.... they shouldn't already have play should they??

Solution : Failing wheel bearings almost always get noisy and start to "roar". If you're not hearing the telltale sound of a worn wheel bearing (and considering you recently replaced both front bearings...) I wouldn't suspect a bearing problem is causing the vibration.

My guess is either you have a front wheel out of balance or an issue with the construction/structure of one of the front tires (tread separation or a belt problem/flaw inside of a tire causing the tire to roll unevenly). (Very) warped brake rotors can also cause vibrations through the
wheel at speed but I think you'd already know if the rotors were warped because they'd pulse badly upon braking. Alignment issues can also cause vibrations at times, but I'd check into the balance and condition of the front wheels/tires first.

Again this is just a share, to be on the safe side, please contact your nearest mechanic.
