Hello, I currently have my rear axel shaft's out and am inspecting the wheel bearing's on the stang. I was hereing a metalic rounding bearing noise when driving at basically all speeds coming from the rear end of the car. After taking out the axel's, I looked and spun the wheel bearings and they look good, and spin freely and look to have not alote of wear. So, I dont know if there bad, and I think I might need a carrier bearing - I think thats the bearing in the front of the rear axel after the drive shaft and big bolt, What do you guys think ?
