: Diff Part numbers



Seattle CTS-V

I'm actually embarrassed to ask this but I can't find the info in any of my searches. Does anyone know the part numbers for the '04/05 diff and the '06/'07 diff? And I can't seem to remember if the diffs in the V's are the same diffs in the V6 models? The guy that bought (and broke) my '05 V has an opportunity to purchase a salvaged diff for pretty cheap but he wanted to make sure the part numbers matched. Any help would be much appreciated!

The V6 has a different gear ratio - 3.42 I think, but the rest is the same. Sorry I don't have the part #.

Here is a quote from James with Lindsay Cadillac from another thread:

15793756 is the new number for the new diff which replaces 10368780 the previous diff...

I vote for this answer because it is the same as that on my differential replacement paper work. (Warranty- no charge)
