As i am driving 20+mph a loud buzzing mix with a rumbling round like possibly a bad front bearing(not sure). it get really loud as i accelerate, around 50mph i cant even hear my mufffler. the weird thing is when i make a right turn doing 50+mph on the highway it gets better. i am thinking its a bad front wheel bearing. not quite sure. also i am not rubbing on anything because when i have my car on jack stand it still make that loud noise. any input would be nice . thnks
