Has this ever happened to anyone? My wife was going downhill, just over the continental divide of course, at over 50mph when she lost brakes and then clutch with a log truck right behind. Some how she stopped. She, our 5 yr old boy and 8 year old dog are still here. I am looking for another rear axle and an 80. It's time to grow up, a little. ( I have a 78 40 for sale or trade on that note) There was plenty of oil in the differential. The truck has 278,000 on it, but I would have never expected this. I have had a little play in the rear end, where you hear a ting before you get going. Perhaps that was a sign. What happened to that c clip? Trade me your 80....
