I have replaced my Craftsman 19mm socket about 6 times. Everytime, it was because it either split, or cracked. In every case, it was because I was using it to loosen the lug nuts on either my trucks or SUV, and yes, I had to use a "snipe." I finally found the solution, whenever I had the wheels on my vehicle get removed by a "trained professional" , I insist that he use either a torque bar or torque wrench, that way, the lugs don't get air blasted to 150+ foot pounts of torque!!! I then test a lug on each wheel before I leave. Since following this procedure, I have not broken any further 19mm sockets, AND, I can now rest assured that in case of a flat tire, the spousal unit and female offspring, can change their own tires without waiting for help!
