I could not find prior discussions about this using search. My car is a '95 Caprice 9C1. While lubing the front suspension recently, I discovered cracks in the braces that connect the frame to the rear mounting point for the lower A-arm (I have pictures but the files are too big to attach). This seems much less serious than the actual frame cracking that some drag racers describe in some of the posts that came up in the results from my searches. In fact, when I am under the car, it takes me back to my '73 Pontiac Grand Am which looked nearly identical underneath except that brace did not exist, IIRC. The hole seems to have stopped the cracking on the driver side, but it looks like the crack is starting on the other side of the hole on the passenger side. My questions are: Is this common? Should it be repaired? What is the best practical way to repair it? I know that just welding the crack will not work. Welding makes the steel brittle so the crack will form again.
