Man what a mess. That must have been a pretty common problem for that brace to have been made.
So what axle does it crack over?
What's the thickness of the brace?
DO you think worn axles agrivated the problem by possbly bottoming out?
Out of ballance wheels?
Do you think the heat from the cross member being welded in may have caused a tempering problem?
DO you think the brace is just moving the problem further back given enough time?
It seems to me it doesn't extend far enough and has the potential to possbly crack at the end of the brace. Couse I see where going any further would involve dropping the pan.
Sorry for all the questions. I do a little welding myself and trying to get a clear idea of what could be done to make it a better repair and what other factors may have been involved in the failure.
