Hi I have a chevy lumina 98 that has a huming noise that sounds like its coming from the front wheels... its a loud huming noise that starts at 20kph+ when i turn right the noise goes away.... i just changes the left wheel bearing but i feel the vibration right under the gas pedal and it sounds like thats where the noise is coming from but I just changed it... what do you think it is?

UPDATE- i jacked up both side and on the passenger front tire there was no movement when i shook the tire at 12 and 6 and maybe 1/8 th of an inch at the 3 and 9 position. the driver side front tired 12 - 6 didnt move much at all but 3 and 9 i could move it easy. any idea?

 

It could possibly the other bearing. Or the bearing in the trans at the axle. Get a stethoscope from the auto parts store, safely put the car on jack stand , have someone get in it put it in gear. Carefully listen for your noise.
