Rear Diff Noise
Well a few months ago I changed my differential oil only the rear and it was fine in the beginning but progressively started getting worse. Not sure if the oil used is too thin or what. Right at 40mph when rpms is about 1500rpms it will hum and vibrate when your off the gas. Reminds me of my Camaro's in the past when the diff was giving me issues or thin oil was put in. Im a 07 E550 4matic.

well, what did you put in there? You may want to do another fluid change and atleast inspect the fluid that comes out. If it looks like its full of glitter, you may want to start looking for another differential.
