Hello, first off i am sorry you are experiencing this issue as it is not a good answer

the bearing for the output shaft for the front differential is the issue, they are a poor design and failed causing a whine or growling about 40 miles a hour, if you put the car on a rack and run it you can use a stethoscope to locate the noise. timken makes the bearings for mercedes and they will not sell to the public. and the bearings are not available in mercedes so the whole transmission must be replaced as the transfer case it made one piece into the back of the trans. it was the worst design they could have ever come up with. so yes the transmission must be replaced.
