Then jack her up and check it out, check for play by grabing the tire at 12 o'clock and 6 o'clock and wiggle it.. If their play then it's garabge, also one other way I check bearing when theirs no play but still howls on the highway is grab ahold of a spring or control arm and spin the tire, if it feel rough then its also garbage.
**Don't do the tip about the spining the tire unless you have experince with it, don't want you to replace it by accident
