Ok, Please dont be mad at me, I did a ton of research but i end up reading 10 page threads with a lot of opinions but not really any clear answers.

I'm in the Army and have been overseas for a while, I just got back and am looking to purchase a CTS-v (2006-2007) but I'm hesitant because of the rear end problems I've been reading about.

Is there a way to fix this? a kit I can buy and have installed? or is it pretty much something where you have to find a really good mechanic and install parts from different vehicles and jerry-rig it together?

I really want one but I don't want to have my hands full with problems. If not a V then I might end up getting a GTO.

Thanks in advance.
