Personally I don't think this is as bad as the wishbones.. well.. not quite as bad..
One of mine cracked after hitting a pot hole. The other I'm not sure.. but probably due to some blunt impact force.
I'm very wary of potholes these days... these cars are fragile...

Trevor, there is steel insert pressed into the casting and its machined to take the taper of the track rod so the aluminium casting is not put under stress.
