[COBALT]

When I rebuilt my rear suspension I took the arms, and brushed them down with a wire brush on a drill to see just how rusted they were. Once I realized they were solid (with some areas of separation, etc.) I took them to a fabricator and had them weld plates on the top and bottom, and fill in all of the cracks, etc.

The only problem was getting those U-bolts and spring mount bolts out. They were rusted solid inside the trailing arms. I had to cut the U-bolts out, and I had to reach inside the spring with a dremel tool, and cut the heads off to get the spring to come off. That meant replacing my spring mounts...

It was a lot of work and I went through several boxes of bandaids.
