Thanks for your time - you are very funny and I truly appreciate sarcasm (my favorite kind of humor)- you made me laugh and that is always a good thing. But you did not have any thing helpful to add. WD40 wears off, it is the law to buckle up in MA, I turn UP the radio to drown out the other noises. Turn blue - hahaha. I am still not buying grinding brakes as normal --- sorry this is the first one many cars I have owned and NEVER heard it before. Glad you love your Edge, wish I loved mine. Thanks again for your input
