2008 E350 4Matic Rear Carrier (Diff) Replacement
So I just got word from my indie that my rear differential (specifically pinion bearing) is to blame for the bearing noise I am getting the rear. I would like to do the work myself and have rebuilt diffs in the past but he says he wouldn't attempt it as they are extremely difficult to get quiet. I trust the guy so I am in search of a used diff to swap in.
Anyone got a hook on one? Have and tips on the repair itself?

These diff's are just like any other diff.......... there isn't anything special about them. If you have another vehicle tackle it yourself. Don't let your indie push away from attempting to be hands on.

I would have been suspicious about any shop steering me away from DIY but I do not get that sense here. Not only did he say don't do it, he said he wouldn't either.

There must be something special about them as even the used ones are incredibly rare. The ones I can find are over $1000. while the diffs for the non-4Matic model are around $200.

Sounds to me like you need to find you a shop that can work on just about anything. A W211 isn't a sophisticated vehicle, drive-line related, at all...

What you have to loose?
I was in similar shoes when differential on my F450 broke.
Had $8000 estimates, but I was able to find factory WIS for the rebuild and bought high-end gears and bearings for about $450.
WIS did call for box spreader, that I could not have, but I took my time to think it over and did the first differential in my life (I have good general experience in mechanics).
It worked fine, but for some time I was observing high temperatures.

With that said, not a single link here has the correct part or even gear ratio. What is required for my vehicle is part #2113509814 ratio of 1:3.27.
Now kajtek1 I really appreciate your post and has given me some inspiration. I am a very good mechanic but this thing has be spooked. It's not that I cant put it back together but its the getting quiet that my indie says is the hard part and all data I see tends to agree.

Attitude? Hmm that is the first time anyone on this forum has said anything close to that about me and how i respond/give input on issues. Just because you are having a bad day or are upset with your vehicle being faulty does not constitute me giving you attitude.
You should be upset with your indie shop telling you he wont replace or fix your rear diff. Not upset with me for trying to help.
anyways. not sure what the gearing is, but here https://www.tlsautorecycling.com/sea...50/194650.html

So a lot of people are having problems with the rear differentials on their 4 matic Mercedes E350's, E550's, E500's and GLK350's. If you are having noise coming from the rear differential, either a rubbing noise sounding like a bad wheel bearing or whining noise, it is most likely the rear differential bearings.
Mercedes only sells the whole differential. The reason I know all of this is because I had this problem with my 07 E350 4matic.
If anyone has this problem and is in the New York area, I am in Westchester County NY, contact me. I can have the rear differential rebuild done very reasonably.
I am updated this from my original post, I have a lot more experience with the rear differential rebuild of this model car and a bunch of other models that use the same bearings. The problem with these rear differentials is the bearings. Especially the outer pinion bearing. And this is true on 2007-2009 Mercedes Benz E350 and E550 4matics, 2003-2006 E500 4matic, 2010 GLK350 4matic and probably other models also. I can guarantee at least those models from first hand experience. When Mercedes spec'd the outer pinion bearing from NTN, they did not make it heavy duty enough and most all of these models rear diffs will fail at some point. -So it is not recommended to buy a used one and put it in because its just a matter of time before that one will also fail. Now available is a new and improved outer pinion bearing that was designed and made more heavy duty and robust, with more rollers. Below is a link to buy them on ebay with many sold and a known perfect fit. Any capable shop that does rear diff. rebuilds can do it. It is pretty straight forward.

There's another source of these parts. Benzexpert.com sells bearings and parts for several models of Mercedes and also happens to be a long time forum member who's a strong contributor to the site, lots of questions answered and DIY's written.

I've never heard of repairing a differential costing so much.
Had my front diff removed, repaired and bearings replaced for ~ $800 including parts here on the west coast. They'll do it for $300 + parts off the vehicle and you can ship to them.
