04r1 Posted October 30, 2012 Report Share Posted October 30, 2012 Looking at a 2007 CTS V. Are these prone to rear diff issues or was that a different year? Anything else to look for when buying these cars? Thanks Quote Link to comment Share on other sites More sharing options...
-Alex- Posted October 30, 2012 Report Share Posted October 30, 2012 06-up have the upgraded diffs I believe. There have been a few threads on them recently, I'm sure some more helpful comments will follow, as well as ignorant ones. Quote Link to comment Share on other sites More sharing options...

Not Brian Posted October 30, 2012 Report Share Posted October 30, 2012 06-07 are the hot ones to buy.. all the good stuff without the price of the 08's and newer. Upgraded rear diff and half shafts and the delicious LS2 engine mmm mm yum. Quote Link to comment Share on other sites More sharing options...
