Can you guys help me identify what caused this?

Was just driving on the freeway and all of a sudden the car wanted to steer to the left and i just hear clicking noise. So i pulled over and couldnt find any problems and when i was trying to merge back to the freeway, the car wouldnt get traction and would just steer to the left. So i had it towed to the shop and they showed me the pictures above.
Note: had the differential serviced on november, replaced all the gasket because it was leaking
