I have only had one that broke. When you spun the tires locked in 4 wheel drive it would make a ferocious clunking sound. I didn't take it apart to see what actually was going on but I figured it was probably the chain jumping around but not sure. The problem with the one I have now is that there is some slack in the chain and clunks when going into reverse. This case has been in full time four wheel drive configuration since 1979.
