I started feeling a vibration in my 2008 hyundai accent while driving at a constant speed. the vibration doesnt 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??
Wheel bearings can make noise and not have excessive play. Vibration is usually tire balancing or a bent rim.
Failing wheel bearings almost always get noisy and start toroar". 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.
If installed correctly the bearing should be fine.
you can check it yourself by raising that wheel off the ground then trying to shake it.
This is only a possibility but your drive shaft might need to be trued or a universal joint bearing on the drive shaft might be bad.
