I need some ideas. 2019 - LFD rack, 270* awning, and skid plates. Above 50 mph or so, I have a very soft and intermittent whine on the driver side. Sounds like a brake wear indicator squealing, but I have good pads all around. If the radio were on, I would not hear it. Gas mileage not affected- average about 19 mpg at interstate speeds. Here's the intermittent part. I can go weeks without hearing the squeal. Then it will occur (5-10 seconds at a time for a few days and the time between events is very variable) then stops again. Any change in loading, such as twitching the steering, light braking, etc causes the squeal to stop. No "pull" in the steering. I've "gunned" the rotors and hubs with an IR thermometer and the temps are typically within 25* of each other. So far, the hubs have no play in them, and no dirt, etc on the brake rotors or pads. My next thought is to disassemble and degrease the caliper pins and backing plates. Could this be an early indication of a bearing failure? Open to suggestions to figure this out that don't include turning up the radio 
. TIA.
