OK. It only happens when the wheel is turned right it gets quicker with speed just a slight turn in the steering like a 1/2 inch and bam there it is. i can feel it in the pedals and the pasenger can hear it as well. ive tried swiching tires around even useing the spare on both sides one at a time. the sound is like a mud tire hum going down the road if the wheel is strait or going left it goes away. please some one give me some tips or beeter yet tell me you have expirenced this and kwow what it is thanks any input is greatly welcome. oh yea i have stock svt wheels and stock size tires stock suspenstion but bat cross and grooved rotors.
