Differential & Transfer Case Fluid Change

Differential & Transfer Case Fluid Change
I have a 2008 S550 4MATIC. I am experiencing what appears to be a violent 'shudder' especially during cornering (high or low speed) and sometimes random low end grinding vibration. I have replaced the two front Motor Mounts and Transmission Mount. That didn't help.
I would like to change the Front, Rear and Transfer Case fluids before I tackle the transmission.
I will greatly appreciate it if someone could point me to the correct direction on a DIY or any instructions to change the Diff's & Transfer Case Fluids.
Thanks so much

If fluid changes do not resolve your problem attached bulletin covers possible causes.

My problem is the following:
I have a CL550 from 2013 which should have the same drive train as the S550
Some months ago I started to notice a shudder when accelerating from 50-60 mph.
I brought the car to a transmission shop and he changed the transmission fluid and added a shudder fix additive.
Since then the transmission is perfect. No shudder and everything working smooth.
Then 1 or 2 months later I noticed the problem described in this thread, the shudder when you turn full at low speed ( like pulling into a parking lot )
So I brought the car back to the transmission shop and they changed the fluid of the transfer case and the rear differential.
It did not help, it still has this shudder when pulling into a parking lot ( after about the 200 miles I driven so far it's getting better but not good yet )
Now I am surprised to hear that the Transfercase is integrated. So I am wondering which fluid they changed?

@autobahnfan How many miles are on your vehicle?
Shuddering can come from:
- transmission or differential friction plates that are failing
- front propshaft U-joint that is failing
- t/case, front or rear differentials that are failing
For the OP's VIN:

thank you for the detailed answer.
When I look at that drawing I can see the TC is integrated into the Transmission.
So I am really wondering now what they did when they changed the TC fluid?
The car has only 59,000 miles. Everything else of it is perfect.

To clarify, incorporated as it pertains to PKAMG shudder during cornering of which first repair attempt would be transmission oil change. As it pertains to you autobahnfan of course TC can be repaired (if this is the problem) by qualified independent but here’s what MBUSA EPC shows for parts using comparable VIN - grayed out.
