Caliper can drag and not heat up the tire. How about the wheel, did you feel that too or perhaps the hub? I have a '91 Camry that had a bad caliper and ground the pad down to nothing. I never heard a thing until it hit the pad wear indicator.
Wheel bearing noise would mean the bearing is going out, but it could be that it just needs tightening to remove excess play. You’ve replaced everthing else, not much left to shimmy.
