hey all,,

I know that the solstice shares it's rear diff with the CTS, but does anyone have the part number for the solstice diff?? 04-05 CTS and CTSV used the same diff and they have nothing but problems with them. They break the shafts and hear a lot of whinning noises for both cars. The 06 CTSV has the upgraded version I know that, but what I don't know is if the NON-CTSV uses the same upgrade and does the solstice also use that upgrade!!
Does anyone have problems with their diffs??

You guys huddle up and let me know :grouphug: ... hahah

Thanks
Jay

yeah,, here's the part number that I got from the dealer, just incase anyone else needs it. Part number 10344863. That's for the rear diff, and the dealer had no clue of what I was talking about when I asked him about the CTS rear being the same(I was just testing him haha). That's why I asked on here first..
