It's not as bad as it could have been, the genuine Volvo half shafts are hardened, which is good in one way but not the other, they are more resilient to breaking.... but when they go, they splinter and the fragments can do a whole heap of damage, quite often the splinters jam into the planet gears and force them outwards a little splitting the anulus ring and if really bad I have seen split hubs, yours has come out of it fairly well off to be honest
