I was trying to find the source of rear clunking noise, and finally found it.(rav4 2003) The cv axle has in and out play where it meets the wheel hub/bearing assembly. (not at the differential) But I'm not sure if it's the cv axle that is the problem or the wheel bearing itself. There is no bearing type noise or symptoms of bearing problems, just clunking noise. Could it still be the bearing or is it just the axle itself?
