Why did my new bearings break

What is your question?

1 have a 1987 dodge diplomat and my bearings broke dut to heavy work trying to get out of snow plus i hit a few curbs. The outer bearing broke and caused the inner to break and my wheel was holding on by my break pads. The washer was sandwiched around the bolt that held the hub assembly and i did not have to remove the bolt to take the hub/rotor off it just slid off. i just replaced the bearings and the washer and seal and it was fine till i hit 55mph and i pit maneuver a state trooper because it broke again the washer is not broke but the wheel is wobbly.so i need to know what torque i nedd ti tighten it to because last time i did 100 and also i need to know some segjestions on what went wrong
