I have a 02' off road. I currently have a humming noise that gets louder as i turn right and goes away if i turn left. I've gone to two different ford dealerships and they insist that it is my wheel barring. So i ended up changing it. The problem did not go away and continues to get louder. Also, i just bought new tires. I was thinking that that was a possibility since they were so bad, but it still hasn't gone away. No one seems to know what is wrong with my truck and i am thoroughly annoyed with paying for false diagnostics. If some body could please be of any assistance, that would be awsome.
