You wouldn't happen to have the torque specs for the bolts that mount the rear differential to the Subframe would you?

what year/model car ?

the attached PDF is the procedure with torques that comes up with the VIN for my wife's 2016 E320 4matic wagon...

ok, then thats the correct PDF from WIS

oh, FYI, your car is a 212.088, so places where it says stuff like... "Model 212 (except 212.074/075/076/077/092/274/275/276/277/292)" would apply (since 088 isn't listed).

I do wish I knew where there was a table clarifying what all the submodels of 212 are... there's a LOT. For example, my wife's facelift 4matic wagon is a 212.288 (and, I believe, 212.2xx are all wagons).

@Left Coast Geek Here is an indirect way via a list of oil capacity for all W/S 212. Hope it helps

Alternatively, looking at the menu selection from XEntry, there is a list of all models under a given designation.

Long time ago I looked at the documents for changing those 4 bushings and I still can't really understand 25.1 amd 25.2 : I marked red



Anyone care to explain ?
To me it sounds like welding new blank thread bore is a must and the bolts are like self tapping ones which create its own thread.

Or the meaning of RE-CUT is like below ?

Thanks

They just mean you need to run a tap through the bolt hole to clean out the old thread sealer from the factory bolts. I did it this past weekend and not a big deal to do at all but certainly did clean out the derbies in the threads. I just used a M12 x 1.5 tap to clean up the threads in the bolt holes.

S-Prihadi

Sweet, thanks.
In my language if I translate it from English, sounds not like bore cleaning with TAP.
Thanks for clarification.

Looks like a popular item on eBay, an aftermarket one seems to be in the $780 range and it fits other cars too like the C class. Could probably find one in a junkyard in a southern or western state with no rust.

hahahaha, I love those 'badges' on the add. Wow, "PROFESSIONAL SELLER"

yeah, i'm going to trust off brand aftermarket chinese steel under my rear suspension, sure.

ccryan67

The part is common to the C and E class, the Chinese repop is not special in that regard. Getting a used one from the SW US isn't a bad idea but there's no guarantee that it hasn't been exposed to road salt or otherwise on the road to failure. Case in point, my car is a TX car now but I had it in the DMV for its first 7 years. I think this component is absolutely worth paying more for a new genuine part.

The warranty on rear subframes has been extended to 20 years. Call Mercedes-Benz USA with your Vin number. You may get a pleasant surprise.

Thanks for the post. Just got the car back from the dealer with the rear subframe replaced under warranty. Got lucky that the dealer was able to get the subframe (believe it is backordered). Found out about the extended warranty by chance when I called the dealer to get a quote and was told that my VIN had the extended warranty on the subframe. MB not really advertising the extended warranty as I did not get any communication from them! Now on to the corroding rear hydraulic brake lines! The fun never stops with the W212s!

Hi. Do you know if this corrosion could cause water to get into the floor of the car? I have a situation where the floor behind the driver's seat has twice now filled with water about 1/2 way up. No water is dripping down from anywhere, and the Mercedes Dealership is telling me that it will cost over $8,000 to fix it (event though they don't know what the problem is yet) or if I submit to my insurance, they will say it's "totaled." It's a 2012 in excellent condition with only 50,000 miles. It happened after driving in the Southern California rains, but I didn't drive through any flooded areas -- just normal water on the roads. Any help is appreciated!

Hi, very sorry to hear about your situation. However, don’t think the rotting subframe is the culprit. Not saying no in absolute terms but very unlikely based on my understanding of the subframe situation. Have they removed the carpets to see if there are any hole in the car floor thru which the water is coming? Are the seats dry? Did it happen one time or happens all the time driving in the rain? Just behind the driver side or both sides of the passenger area? Rear doors properly sealed? And is the moonroof properly sealed? Keep us posted on what you find out.

cetialpha5

That's usually the sunroof drains. They're probably clogged with debris so water gets into the cabin. You should have those cleaned out. You should check the other forums also, these threads are mainly for the E class but the concept should be simliar.

Thank you for responding. They want to charge $8,000+ to remove the carpet and seats to "find the problem." Yes, it happened once before in March 2022 -- same exact problem, same place, only the well behind the driver's seat & not up on the seat. Seats are dry. NO sign either time of any water dripping down from anywhere. All seals are fine. The Dealer says the car is "totaled" because there are computers and wiring under the carpet area that could be damaged. In March, 2022, they just dried it and said they couldn't find any problems. My insurance is saying it's totaled too for the same reason. I'm distraught because the car is in excellent condition and only has 50,000 miles on it and I just put 4 new tires on it last year. I was wondering if I should take it to another Mercedes dealer and have them replace the subfloor AND ANY OTHER DAMAGE IT MAY HAVE CAUSED. If it corroded underneath, could it cause water to pool in this area? Any suggestions are welcomed! I also noticed that other Mercedes models (324,000 of them) are being recalled for water accumulating in the spare tire wheel wells and causing damage to the fuel pump control units. Could this be related?? Is the spare tire wheel well on the left side of the car? I'd check, but my insurance has taken the car.

juanmor40

An example, all recent MB are designed similarly


Is the front footwelll wet as well? Or dry? If dry. I will check B pillar and headliner for wet spots. Still dry? Check door seals are not worn, dried and allow water in.

I do not recall if the W212 has drainage on the floor, usually with a rubber groomet. anyone has seen the floor w/o the carpets?

Left Coast Geek

the spare well on our E350 wagon is centered under the floor of the trunk and I believe the E350 sedans are the same.





You mentioned a C350, I'm not sure what those are like.

I was just informed that my car will not pass PA State Inspection because of this problem. I company that inspected my car spoke with the local MB Parts Manager's and "'it's supposed to be covered by MB Extended Warranty (based on product VIN)". I have an appointment with MB to correct this issue. I'm trying to find out more about this issue, is the complete repair covered by this Extended Warranty or just the part(s) involved.

Baltistyle

It will be fully covered including labor.

jhopper9

Thanks I hope so.

My car will no longer pass PA State Inspection. I just spent $1,775 to get my car Inspection and had to get for 2 new tires, new front brakes, pads and rotors, oil change, etc. I was informed that based on my VIN, it is covered by an Extended Warranty, and I have an appointment to get it repaired.

juanmor40

Just be aware some "stealerships" will try to oversell some additional "repairs", not covered by the extended warranty, while your car is in. So be mindful, if those are really required or that you can outsource at a lower cost later
