Just in case anybody knows anyone with a G8 (and perhaps for those who were wondering WTF the problem was from the other thread)... The suspension issues have been fixed.

Not only were the strut mounts bad, but the LCAs had some issues with the rubber seal (as I suspected through research) that caused the joints to fail. I got the General to replace them out of warranty at no cost to me, so at least it was settled fairly. The rattling problems are all gone. Thank god, I was getting really really annoyed. I wonder if anybody has paid the 1000+ it would have taken to fix both issues....

Maybe someone knows a person who is also at wits end with the problem...
