I have a 2012 C300 4Matic with I believe the same problem. I have a rotary thumping sound suggesting a rear CV or U-Joint. Center driveshaft mount and rear propellor shaft joints all check out. Very helpful video. It's nice to see the parts without getting greasy.
It's great to see you work on such a wide variety of transmissions and to see you do the build-ups in addition to the tear-downs. The other transmission guys on this platform should take note. Thanks for the excellent content.
Hey Gary, you can get the front driveshaft out without dropping the transmission, you pull it forward. It involves taking the exhaust and some bolts off on the front diff. There is a fillplug on the transmissioncase for the transfercase. You prefill it with 700ml. If you don't, the level will not be correct. I takes a very long time for the oil to get to the transfercase thru a very small hole in the oilcooler returnline that comes into the transfercase. Also that long bolt is onetime use. By the way, your videos are always good, keep them coming.
@@GaryFerraro It should be on the right side on top of the transmission, it's not from the side. It's a 6mm allen plug, looks the same as the plug in the oilpan.
The outer bearing races are spinning in the case on mine. The outer races are spinning in the case, is this normal? Since they are spinning I would expect them to come out easily but they do not. How do they come out?
@@GaryFerraro actually I had a wrecked transmission fron my former E63 and the gear was fine. Thst being said they sell them now for ~$600 shipped now.
@@GaryFerraro it is still part of the transmission case. The difference is the transfer case output shaft, clutches, planetary gears, and ring gear. The sun gear I believe is the same part. Thank you by the way for posting these videos up!! Liked and subcribed!
Hi Gary thanks for a another informative video I like your approach to something you've never done before the way you got in in dismantling the transfer case , confident and cautious Thanks again
I have this exact issue with my car, 2012 mercedes e350 4matic. It has been impossible to find the parts and, like you mentioned in the video, everyone is trying to sell me the entire transmission instead. Any chance you're open to referring me to the used parts company you were able to get these parts from?
Was there a clonking sound, or a grinding sound, my car sounds like is has a bad wheelbearing, just grinding under pressure, goes almost quiet when i let up the accelerator.
Awesome video! Do i need any tools to remove any of those bearings? What about installing them - any tools. Lastly, how did you reach the too bolts of the transfer case - there is no room up top. Thank you!
Good video Gary. Strange design though. So how do you think MB assemble this part? Surely there is some way to disassemble it too. Is it pressed together, are there signs of it being welded together maybe? There must be a universal and not a CV if there is no method of sealing it to retain the grease a CV joint would need. Thoughts? How much do these things cost?
It can be but you really need to be familiar with how to do it, there is a seal that can tear easy so we pull out the front drive shaft, if not familiar not sure i would attempt it
So the transfer case needs ATF separately ? Or it share's the transmission ATF ??.........I changed my ATF and filter......my 2008 c300 4matic always had like a clockwork noise but it changes gears good doubt it's my transmission doing that noise I'm not sure
The transfer case DEFINITELY uses its own fill and drain plug. WARNING do not assemble this unit and add fluid through the oil pan, you will be sorry. I have quick video on how to do it on my channel.
Thats not the same T-case, that maybe the one on the ML series. This one i'm working on the Transfer case is part of the transmission case, all one piece, all common oil
Kind of a goofy design. I'll take the American way: with the u-joints/ prop shafts outside the case where they are cheap and easy to change.. Maybe they just had space restraints and this was what they came up with to make it more compact. I wish you could have got a close up shot down inside there, or cut the old one in half. I'm just curious as to how beefy it looks.. and is it a "u-joint' -- or more of the ball prop, like a CV joint.
I just got another 30mm 12 point from NAPA and it same with as Autozone it loose it shifted right to left around 4mm. I didn't want to risk rounding the nut maybe I would buy MB tool around $170. Did you notice that 30mm Snap on also have play around 4mm? Did you use chisel to open the lock in nut before you impact or you just drove it with impact wrench?
@@GaryFerraro Thank you for responding. I did research and most claimed they just use impact to bust it open because it not lock to threads so will not harm threads. I did loose it using impact and it takes only under 2 minute to bust it open. I used Hazet tool designed for mercedes and bmw flange nut. It better than Autozone and Napa. It still had play around 2mm but i think it designed that way impact had momentum to break it loose.
Gary, I had same problem u-joint for front drive shaft damaged loose and rattle. The flange nut that you have to open first need 30mm 12 point deep socket with Mercedes part number 126589020900 and the torque spec is 200nm. The mercedes part is cost around $170. I got 30mm 12 point deep socket from autozone around $20. But it not really fit tight and I don't want to round that flange nut. Can you tell which socket you use to open flange nut in transfer case?

Gary I did installed new side gear for the front drive but I found out the boot in front drive shaft is not fit properly and it leave gap around 3 mm. I just wonder should I reopen the transfer case and do something to make the boot in contact with transfer case without any gap.
@@GaryFerraro Yes it not seal only cover that from water but not really tight so I just wonder why I could not press it against the case it always had gap around 2 or 3 mm
