now that i've read this thread, i feel confident that greg has identified the problem and has a fix that seems to work for him. however, there are others here that are saying to leave it alone and that the diff sound is normal. what should i do here?

i have 2800 miles on my car now and also did not experience this prior to my 1200 mile service.
If it bugs you, get it fixed. It will "cheapen" the car in your mind (and others). I seriously doubt there is much difference in limited slip action by going to the quieter fluid.
