Rear Diff WTF?!?! 2002 GT 5speed

OK so I had a noise in the rear end and after reading numerous forums I understood it to need the fluid changed. So I tok it to my guy along with 2 quarts of 75w-140 and a 4oz bottle of Friction Modifier. He said the old stuff came out looking like a milkshake so he cleaned it all out, put RTV sealent on and cleaned the crap out of the diff cover and reinstalled it. I drove the 25 minutes or so home and just as I get home it starts that dang noise again at very low speeds, ie...when pulling into a parking spot or making turns at a light or stop sign. It is kind of a whinning and grinding, nothing very loud but I know it is not normal. Any ideas? Stock everything in the rear btw! 115k miles as well.

I would agree with the above. Good time to upgrade

This is one reason why I havent changed my Diff Fluid (150k on it probably), although nothing appears to be wrong at the moment. My wife would not like me buying gears and tuner at the moment
