My wagon makes a stuttering noise in the front when cold on 2005 Mercedes-Benz E500 4MATIC

When I pull out of my driveway in the morning and turn my steering wheel all the way to one side, the car makes a stuttering noise and it seems to be dragging. It was a very small noise at first and over the past 6 months got louder. The funny part is that this noise goes completely away, as soon as the car gets warm. After driving it for ca 15 min I can neither hear the noise nor feel the dragging in the front. It is not a clicking, it is more a stuttering dragging noise. Had it at two different dealerships and one independent European car shop, they told me three different stories. 1. Thought it would be the CV joints (however, car has only 50,000 miles on it and 2. guy told me that is highly unlikely with so little miles. 2. Guy said that it could be something with the transfercase fluid and that I should simply get the fluid flushed and exchanged. 3. Guy is telling me that it has something to do with axle shaft and traction control system. Ok, three people, three different answers. Still don't know what I should do with this car. Anyone has another idea or had a similar experience. I would appreciate it. Thanks.

Perhaps best to post on a Mercedes specific site. I have seen CV inner joints make strange hard to diagnose noises but would agree that the mileage is low and the roads in Palo Alto are in pretty good order.At 50,000 miles just as a service item I would try changing the transfer case oil, I have heard of the problem with some Jeeps but have experienced the problem myself on Honda CRV's if the oil breaks down or the wrong oil is used by a quick lube shop. I see a Mercedes number for the front and rear differential appears to be a hypoid SAE 85W 90 oil, the transmission is specific to Mercedes but could be either of two transmissions.

The fuild in the front differential may need to be changed. Do you know if it is limited slip differential?

I don't know if it is a slip differential? How can I find that out. Would that be the same fluid that comes from the transfer case? I was told that I should change that, as one of the possibilities. Thanks
