I can't help you with your busted transfer case, but the getting it into (And out of) 4WD...…..I have a 2015 Sprinter 2500 4x4 and recently I had a major clunk sound and then basically it would not stop and felt like there was a broken gear in the transmission and I think my transfer case has something broken, unfortunately out of warranty I am trying to gather the most information to
1/ find parts cheaper than dealer pricing
2/ Have some info from whoever experienced that same kind of issue and learn from them what was sone to correct the problem.
3/ I bought the unit used and I never have been able to switch easily to 4x4 and it sounds like not a isolated case, what did people do to improve?
Thanks in advance

Thanks for sharing. Where did they apply the lub? on the driveline spline?My 2016 Sprinter 3500 170EXT 4X4 had the driveline clunk & whine from new (May 2017) This summer MB authorized my local MB dealer here in Texas one by one replacement of the transfer case & all the drive shaft assemblies. Interesting they monitored each change with audio recordings that were emailed to Stuttgart. After a month & half of analysis MB instructed the dealer to not use LocTite & had them pick up a can of Motocraft PTFE Lubricant from the local Ford Dealer (its the same stuff that Ford used to solve their driveline clunk in at least the 2011 F150. The Ford dealer of course needed a week to get it from Ford so I got via my Amazon Prime in 2 days for less than $30.00 The MB dealer applied the PTFE & it has solved the problem flawlessly for over 2000 miles thus far.
yeah because the whine is from the front differentialNew T case installed under warranty. No change in gear noise/whine
That sounds exactly like mine. They claim it's normal. I've ridden in other 4x4s that are not as noisy. It's frustrating driving it at 35 mph as it really resonates and is noisiest at that speed. They refuse to do any work for it so my suggestion is take it in a few times. At least that way there is a well documented paper trail in case something happens outside of your warranty period.Hi I am new to the forum. I have a 2019 4x4 MWB Sprinter with the same noises including the clunk. I also have a vibration through the steering wheel that makes your hands go numb after a while. My dealer had the car for three weeks and changed a bearing that had to come from Germany. This did not fix the problem. KiteSprinter did you get your Sprinter fixed and if so what did they do. Below is a link.
Thanks
The issue is no matter how good your paper trail outside of the warranty Mercedes isn't going to fix anything for free 99% of time. This is where the dealer comes in so when you get your van serviced bring the service manager donuts and coffee, chat for a bit because when it comes time you need something outside the warranty they will go the extra the mile. I found that Mercedes refuses to acknowledge their vans have issues because it's a Mercedes so must be perfect.That sounds exactly like mine. They claim it's normal.

Sorry to hear and I feel your frustration. It's not a great design and the droning happens with mine even the fix but I just got used to it. In my opinion these vans are not that great. I have a bunch of friends that are contractors and they have the worker vans and they all say the same thing "they are garbage and have very little power" they also don't like the throttle response and I told them about the pedalbox to help. So far about 3/4 of them sold theirs and bought a different van. My pump just went and I was just outside of the warranty and you don't even want to know how much that cost me. Keep us updated on if you bring it back to get serviced.That sounds exactly like mine. They claim it's normal. I've ridden in other 4x4s that are not as noisy.

OK so after getting frustrated at the noises I decided to look into it myself.That sounds exactly like mine. They claim it's normal. I've ridden in other 4x4s that are not as noisy.

That's quite the write up. Did you have a third party look at the van or was that your summary to the dealership? That matches the homework I had done originally and pointed to the angle of the prop shaft.OK so after getting frustrated at the noises I decided to look into it myself.
I have attached what I found in the pdf but basically the uni joints are out of phase, the pinion angle to rear driveshaft to first drive shaft is incorrect as is the first shaft to transfer output shaft. This sets up a resonance and vibration. I also did a vibration analysis as well. The car is in with the dealer to be fixed. I have to say that the dealer has been great and is trying to get Mercedes Australia involved but they are finding it difficult. I will be checking all angles etc when it comes back. The car is only a month old so I am loath to fix it myself and have Mercedes void my warranty but I feel it is an easy fix.
Enjoy the read
Hey Kite Surfer.That's quite the write up. Did you have a third party look at the van or was that your summary to the dealership? That matches the homework I had done originally and pointed to the angle of the prop shaft.
Mine was frustrating enough that I took it to a lemon law attorney, however, I had already done some significant work converting the van which made that about out of the question. I am really hoping you get yours resolved. If so, there would be a documented fix which would give me more justification for the dealership to work on mine.
