Ok I had it on the lift tonight with the wheels going. It coming from my l/f wheel. I removed the wheel, removed the caliper cause I had funny looking ring around the rotor near the hat. Figured a rock or something got caught up in there. To my surprise nothing was found. I removed the brake pads cleaned them up really good and lubed everything back up. Figured hell its getting late, so I put it all back together. 5 mins into my drive home its still doing it. Give me some more time I'll find it... Hell it may be a bearing, or a joint but I don't know how.
