Rav 4 wasnt a wheel bearing. I wasnt sure. So i grabbed my kit, clamped microphones on all 4 hub mounts and went for a ride. Then on rear diff, center support for rear driveshaft and transmission output. Still couldnt pinpoint. So put sensors on calipers and right front axle support. Four times on hoist, four road tests. Finally, right axle is the culprit.
