What in the Hell could this be? I just found another leaking axle seal and now this? What a day! Please any help would be greatly appreciated. When I come to a complete stop I hear a grinding noise or something similar coming from under the hood. Once I start going again it seems to go away. It does not start right away when I stop but after a few seconds? Could this be some sort of fan issue or AC issue? It almost sounds like a knocking grinding noise but I don’t think it is coming from the motor. If you have any idea of what this could be please let me know.
