My guess is that it cracked because we did not have it hot enough but well, I still have to learn a lot because this was just the first.
The problem is that we do not have many axle's avalible, hardly any to get here in Germany and the shipping from the US to Germany of an Axle from SID is just a little over my budged =(
So I went trough all the pain of trying it myself, well what else should I do when I like to have my baby dropped ??
