i made a right turn very slowly onto my drive way and i got this metallic noise/metal scraping noise (almost like a heat shield that is rattling/being scraped by something. is this cv joint? also i am hearing this strange noise that at first i thought wheel bearing but i just put on snow tires also it is like a whirring noise that increases the faster i go. the whirring noise did not happen until i went to a snow tire ( blizzaks). the other metallic scraping noise was there before and after the tires where changed. any thoughts or is it time to take her in for a look?
