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.

This may sound retarded, but have you looked for any loose hoses.plastic panels or anything else like that? Sorry it all I've got right now

I looked over it and i haven't found any hoses or anything loose. I still haven't found out what is wrong with it, but thank you for your advice!
