When I had my bearing go bad, you couldn't feel it by grabbing the tire. I had to do a load test. As you drive at maybe 20-30 mph, try steering the car left to right. Think they call it loading the bearing. If your steering to the left and the noise gets louder, it's your right bearing. If you steer to the right and it's louder, it's your left. You say your wheel bearings keep going bad. Are they a good brand and are you torquing the axle nut to spec? When I first had the car and had someone else change the wheel bearing, they torqued it down with an impact and it looked like they were making it kind of tight. 6 months later, the bearing failed. I changed it myself next time and torqued to spec. Torque varies by year. About 70k miles later, the bearing is still good, just have problems with the wheel speed sensor wires.
