Fix Mercedes Differential Leak, W210 W220...

If your M112 or M113 differential pinion seal is leaking gear oil, then you can avoid one of two things by watching this simple step by step video and doing it yourself:
1) Doing nothing and letting the differential get destroyed - costing you thousands later.
2) Letting the dealership or a mechanic do it for at least several hundred Dollars if not over a thousand.
I am listing the tools and parts you need in the beginning of the video.
Your cost will be around $10 for a bottle of differential oil, less than $30 for a socket (if you don't already own it), and $8 for the seal itself as of May, 2024.
The car in the video is a 2001 W210 E320, but the same procedure applies to the W220 S class cars and many other Mercedes models of the era including SL-class, GLE-class, C-class, CL-class, CLK-class, GLK-class, ML-class, SLK-class, and GLS-class. The only change will be the size and type of the socket to get to the seal.

Many dont know this but you need to grease the threads on that three jaw puller. Look close, those are all metal filings flying off the threads on the puller shaft where it spins in its bolt. Plus takes away much more friction so impact doesnt have to work so hard. These tools get ruined fast when no one greases threads. Its a common thing. Many buy ball joint removal tools and threads they come dry out of the box. Buyers go at it and on first ball joint they do, threads get destroyed and then they complain and give a bad review of the tool. They just dont know.
Just sayin! Great vid. Always well done. Thanx 👍👍

Hi John, thanks. You are making a very important point. I failed to mention it in the video, I think.

Another great video! Would you mind to make a video review of the lift you have? You have a similar awesome video for the Milwaukee torque wrench that I bought right after you uploaded it, the same could happen to your lift too, seriously 😂

Thanks, Igor. I will keep that in mind. Some others have asked for a review of the lift also.

Am i imagining it or does your car also have flex discs where the axles bolt onto the differential? If so 🤔 hmmm! Interesting!

No, you are not.
