I have an ml 320 cdi 4 matic 2007 suv. On hard acceleration, it makes a grating noise. I assume it's the transfer case. Mercedes Italy told me that my model does not have a transfer chain and the whole case needs to be replaced at a huge cost. Someone else said it did have a transfer chain. Anyone know the answer - does it have a chain or not? Thank you.
Before you start believing a M/B dealer, change the fluid in the T-case and see if the noise diminishes. It appears that there is no chain listed but that mean that M/B does not service it. In W163 they did not show a chain but Borg-Warner made a chain for it. So search the internet and see if a chain is available.
Also, your problem could be the center support bearing in the main drive shaft or a faulty front drive shaft.

Indeed we are, which is why I posted a link to this extremely relevant video, which, as one can clearly observe (if one simply watches this video) is the focal point of this video. And that focal point is that the transfer case is integrated into this transmission, which is a 722.9 transmission on the OP's vehicle (W164), which has no chain, which is not relevant to a W163 which uses a 722.6 (and separate transfer case), which appears is what your drawing is from. In fact, one can clearly see that the output for the front driveshaft is from a helical cut gear directly meshed with it's mate which is fastened to the transfer case gear train, and that this whole assembly therefore comprises an integral transfer case.
I'm not the one that named the video, nor am I the one that made the video. If anyone has issues with it being called "transmission" and not "transfer case", they might want to make those comments on the YouTube video.
In fact, this YouTube video might even be extremely relevant for the original poster of this thread for all I know, since evidently the author of this YouTube video was having noisy bearing issues which often produces a "grating" noise.
You know very little about W164 MLs and as a matter of fact, you know even less because you own one. All W164 MLs have a chain in the Transfer Case.
The fodder that you posted so proudly as ammunition has now become animal fodder. GLKs have their own separate site and a different vehicle altogether. That veh. has the Transfer Case integrated in the transmission, BUT THAT IS NOT THE CASE WITH W164 MLs.

Aww.
God bless your heart!
And I sit corrected, because you are absolutely correct, albeit a humongous **** weed, which is no doubt related to your geographical location.
To the OP: Sorry for the mis-information. I verified that the ML320 W164 does indeed have a separate transfer case by taking photos from underneath the vehicle.
"Posted so proudly" - really? Is that called for? Are you such a funkwad that you've never made a mistake? Anyone ever tell you that you are a true dick head in your mannerism? Not one time in what I wrote did I get combative in my response. What'd you do, chief?

To the moderators:
Please remove my profile. Ban. Block. Whatever.
I've got no time for forums which support such crass ash holes such as what I've seen how this dick wad responds to people.
Thanks!
I'm with Maj. Dundee on this.
I had a bad"center support bearing", commonly known as a carrier bearing. It made all kinds of noise...One indie said itwas the transfer case, the other mechanic said ALL my wheel bearings were shot....and it turned out to be the carrier bearing. I replaced it with a 25 dollar cheeepeee....and of course it went bad in a year, and I had to buy another one.... but the point is ...it mimicked all sorts of problems
I heard a for sure bad transfer case once on a 2004 240( ?).....I didn t buy the car because of it. It went" clickity clack" accelerating on turns from stop. It was the transfer case.
The seller changed the fluid ( using quality MB Fluid) and the sound went away. I also heard it only works once, and if it's not too far gone....and use only OEM MB Fluids for this . Hey, it only takes a couple of qts.
Aww.

A mistake is doing it once. Then you doubled-down with an arrogant display of terminal ignorance, going so far as to imply Dundee doesn't know how to watch a video. Don't let the door hit you in the a** on the way out.
No, I am not. On hard acceleration, and only on hard acceleration sounds like the chain is slipping, - a kind of grating sound. It is for a very short time only then it seems that chain has engaged with the sprockets - otherwise no noise at all. This is my first time on this issue.

Have you considered removing the transfer case, opening it and inspecting the chain?
Truck must be on level ground or on a lift. First remove the fill hole plug, then remove the drain hole plug. Then replace the drain plug and pump in 1/2 qt. of fluid and replace the fill plug.
Thanks so much, Maj. I have changed the oil in the transfer case, but it made no difference. The ratcheting sound continued on hard acceleration. Tha's why I'm assuming it's the chain and or sprockets.
I had the same problem on a 09 w164. Ordered a new chain on the Internet and stripped off the cover on the transfer case. Fitted the new chain ok but two bearings and output shaft seal needed. I got them through a auto gearbox repair company.
none of these parts are available from your mb dealer. Car is fine again.

A link to the auto gearbox repair company would be nice.
ME TOO....I had a bad carrier bearing and it sounded like all 4 wheels had bad bearings.......BUT it did not make the "Clickity Clack"
I witnessed a guy change the fluid and his "clicky clack" went away....2004 MB something or other....
It it said.....You can do it ONCE.....but it wont clear it the second time....Use the specified MB fluid for the change - only!
