Driving home I hear an uneven grinding/knocking noise coming from the front passenger side with the windows down and driving about 10-15mph in traffic and also makes the same noise when I need to stop. I could feel the grinding inside the car. Its not a squeak or from a dusty brake pad or rotor(changed a week ago) and I also replaced the driveshafts. I don't know what it is, I'm confused and annoyed and it's been happening for a couple of days...Can someone help me?!?!?
