steering vibration when turning
Over the next two weeks it became significantly worse. So bad, in fact, that I was hesitant to drive it. So MB picked up the car again and inspected it. Decided to put in a whole new DRIVE-TRAIN!!!! But an entire drive-train can not just be shipped in. They have to have it brought in by a flat bed truck. So now we are waiting for MB to have it brought via a semi. I have the car back and they swear I wont hurt it (or me) by driving it. But the shudder keeps getting significantly worse and at higher speeds, and less turning radius. It can't be good for any components connected to the fault can it?
BTW, my dealer called MBUSA and they were told that the problem appears to be with the transfer of energy; something about the energy going in, isn't equating to the energy coming out.
I'll keep everyone updated.

Thanks.
Thanks.
I think the problem is finally fixed. No more shudder when turning tight & slow. If there are any more developments, Ill be sure to post about it here. If you don't hear from me, all is good.




Thanks.
I had the same problem yesterday and the dealership tried to BS me, saying the spark plugs needed changing. My car only has 78k mi!! The sparks plugs go to 100k.
How did you convince them to change the transfer case? They only offered to change out my fluid. What did you have to say to them, or how did they chain of events go?
Thanks for your help. :-)
I'm having the same issue.
Problems:
1. Vibration when turning the steering all the way to the left or right, tight turns at slow speeds etc.
2. Jerky shifts from 2-3 or 3-4 as well as down shifts.
Back in 2017 around 46k , they did a software update and in a week time, the issue is back. They replaced K1 Clutch pack and did a tranny rebuilt under factory warranty.
Fast forward 65k miles 2018-2019, the issue is back. Steps like firmware update is repeated this time as well.
Currently vehicle is at the shop and hopefully it will be covered under ELW.
BTW, it doesn't matter the temperature outside. I've had this issue in summer as well.
Now, a silly question: Does this comes under a lemon law? My warranty will expire on June 2020 or 100k miles. I love this car and I want to keep it as far as it could server me.
They said that if I don't fix this, my whole transmission/transfer case will break. Are they trying to scare me or is it true? What happens if I just leave it?
Thank you!

Yes, obviously repair is needed but I personally don't think it is as bad situation as they make it sound like. What the problem with planetary carrier I think is with the clutch pack that I understand is built into it. This clutch pack would be the center differential lock between front and rear axles. You feel the shaking / vibration at turns because that is when you generate speed difference between front and rear axles and the differential lock has to slip to allow this speed difference. The clutch pack is going bad and is not allowing for a smooth slip.
The problem obviously is that during original manufacturing the clutch pack is not lubricated properly and this is why the service bulletin specifically instructs to soak the part in oil before installation. This is to soak the clutch disk friction material so it is properly lubricated.
I don't know in detail how MB built this part. If it is built very cheap way (would be hard to believe from MB) the wearing clutch pack would allow the gear wheels shift sideways and possibly allow them to come in contact with parts they are not supposed to come in contact with. I don't believe MB would have made this kind of design so the problem really is that the friction material layers on the clutch disks are wearing and when totally worn then you get metal to metal contact that would not be good as this could cause bigger issues but even this to me does not sound really a catastrophic failure. You would not have center differential locking basically at all but in dry conditions this would not be an issue.
Found the below utube link. It is about a S-class transfer case but I believe it is built the same way on E-class.

The car is a 2014 C300, but with 195,000km. It's my understanding that in the W204 model the transfer case is attached to the transmission (and uses the same fuel) so it's harder to service.
I bought it used, it passed an inspection at MB but this was the only thing they found. I don't put in more than 5000km a year - should I pay the 1600$ + tax to fix this in your opinion?
