I just replaced the front rotors and pads on my 96 Bronco, I also repacked the wheel bearings. I had to remove the ABS ring, which i pressed back on, that all went smooth. Now when im driving it has a ringing sound, its constant and its really annoying and irritating. When I assembled it all togather with the pads, new rotars, nothing was rubing ont the heat sheild, what else could be causing this? It stops when I stop or down below 15 miles an hour. Could it be the new pads rattling around in the caliper? Its just really got me heated now at the moment any suggestions or help would be really helpful.
