Jep, that is right, it did crack a little like 6 or 7 litle spots on the lower ridge on one side. I just grinded them to see how deep they where and they are about 2-3 mm deep. So I put a weld on it to get the truck running again till I have dropped a good one =)
I just got a hold of an other axle in Germany and like to try it again later, if it doesn`t work I will finally get one from SID.
I made my steering arms longer, welded a piece inbetween. I put the pictures in later.
