I unhooked one side of the sway bar (AKA rear lateral bar) and was able to get the coil springs to seat again and drive around the parking lot. It's still a few inches off center, though. I wonder if the stabilizer bar needs to be replaced too- it doesn't look like it mounts firmly enough to the frame to be causing that kind of problem, though. Could the coil springs themselves be bent? I hope the frame isn't.
