Thanks for the pictures and words of warning, I have a 2 month old and would dread the thought of this kind of a failure at highway speeds.

Can you give a detailed description of what a spring perch is so others can inspect. It sounds as though it's the Lower "A" Arm, where the front coil spring is seated? A schematic drawing would be great. Are these parts manufactured out of stamped thick sheet metal and spot welded together to form a part?

Thanks again,
