Does anyone have a GM service bulletin for the rear differential leak in the 06 V8 STS? I'm getting a bad whine from the back end of my car every once in while and knowing my luck if I let the service advisor take it for a test drive it won't make the noise

check out the rear diff leak here as there are many comments including at least one SB but don't remember if it included the V8. At least you many get some good ideas/responces out of the many pages of replies.
