I have replaced my driver side rear wheel bearing 3 times now. Each time after about 6 months the previous bearing has gone bad. I have even replaced the differential thinking that it might somehow be causing the problem. Every time I replace the bearing I get a couple good months, but then I start to hear a popping coming from the wheel when I start to accelerate from a stop. I feel like there must be something that is causing this continued failure. The Hub was also replaced twice with the new bearings.
