I have successfully skimmed the mounting face on an A7 diff where there was axial run out caused by a previous pinion failure -that diff had about .005" TIR -The diff was running between centres in a lathe when I skimmed it. I think that having any run out there would make it difficult to get a consistent pattern when setting up the mesh and depth of engagement.
Did you check the pattern with engineers blue or chrome yellow when you built it up? With a well used CW & P I have found that getting a good pattern is the best way to get silent/quiet running; setting it up according to the book/numbers etched on the pinion etc. is going to lead to the CW & P pair running on high spots if that setting doesn't match what's been happening with the gear setup for thousands of miles previous.
