I had another thread in a different category about this problem.. Just in the last few days my drivers side has created this sound.. It sounds like something is vibrating.. Like a think metal just vibrating.. I've taken the wheel off to see if anything could be lose or what not.. Nothing.. Someone also told me that if i was to for instance, turn left and the noise goes away, it's my left bearrings..well, i tested that theory.. It still makes that noise.. The hub assembly is exspensive and I don't want to change it out and it not be the problem.. Anyone have any info? thanks
