Finally did mine today. At 64K miles, all fluids looked OK. At least with my driving style, 60K replacement interval is fine. To gain extra space, I put the truck in the raised position and put 4 jack stands all around just in case it decides to low itself. Took about 2 hours at a slow pace.

The differential drain plugs do NOT fit with washers. Rather, there are o-rings, and I for sure did not reuse 11-year-old o-rings. New drain plugs from Mercedes come with new o-rings.

on my 11-year-old car with 75k miles, both diff fluids looked like new, the transfer case fluid pretty good.
