- Replacing the rear differential in my Mercedes ML500 w164 2006. Changing the bearings, seals, cleaning and mounting in the car. The old differential was completely destroyed, it was not profitable to repair it, the costs were too high I replaced it for a different one from the Mercedes W251 with a gear ratio of 3.70, the same as in the damaged component at the end of the movie, there is information about part numbers

Clean, professional and entertaining 👌 classical music section adds to the video's beauty.
Nicely done.
thanks :D
Sir, you are methodical with great attention to detail. I just send it to my mechanics so they enjoy your workmanship. Thanks for posting.
Everything looks so clean at the end holy
Great video, chapters would be awesome!
Great video! Thanks for sharing.
You Are definitively my best GAY!!!
a Super work, great job for videos, and sounds... Plz never delete your CHANEL... We need people like you ... I appreaciat that you upload your UNDERSTANDING
Thank you, I'm glad you liked my films, I promise to record another one. I have many ideas :)
No no no my friend why do call him GAY? I think you probably wanted to write GUY, ain't you?
@@malan07 So sorry about that, i am French...when i wrote the comment, i did not seen my mistake... my apologies for my bad English
Excellent video! That's what I need!
I am glad that I could help :)
Thanks for video!
Excelente video y excelente trabajo. Muy didáctico. 👏👏
Tanks:)
@@mymercrepairs1097 Great job. I have the same sound when changing from D to R. I feel loose. Change chain transfer case. The same.
Cleaning with paint thinner is better than with brake cleaner. It doesn't evaporate as fast and when rinsed off it leaves a protective film on the parts. That`s also a good way of cleaning valve covers and engines in general.
Thank you very much
Great video. What issues did you have that you suspected that the rear diff was the cause?
Great work. Do the bearings also fit in the Offroad Pro with lock?
Nice work... Thanks for sharing
thank you very useful video.is it they same all ml w164?
Thanks for the video, very informative!! Do you know uf the job is much different for the front diff?
The front differential is very similar to the rear one. Its repair is not much different from the rear one. Often even the bearings are the same
Excellent. I have a few questions, if I may. Why does Mercedes does not include differential oil change in their maintenance booklet? At least the booklet that came with my W251 (2012) does not have any reference to it. At what intervals would you recommend replacing the oil? What about transfer case oil? Should I use the same oil you used on this video for both? Thank you for posting this (and some of your other videos).
Mercedes says oil will last a life time. Normally it should be changed every 60 000km. Same as the oil in the gearbox.
How did you remove the bearings? Had to use a tracker?
Thanks for your excellent video, looks the rear flex disc has got cracks, would u replace that?
where do you see the crack in the flex disk? I have controlled this item and it is good
Thank you for this great video. I need a bit of advice. The differentials, front, and rear, on the
Mercedes ML and R Class are non-serviceable. Or should I say, Mercedes
tells you that I do not provide torque spec for it. So how low pre-load
torque would be safe? Since a too high pre-load can be very bad.
Of course they are repairable, but it is not always profitable. If only the bearings are damaged, they can be cheaply and easily replaced, if the gear is damaged, the costs increase
@@mymercrepairs1097 I have the tools. But not the torque spec, or backlash spec. What would you do?
Do you happen to know the rear differential pinion bearing part number?
Out of curiosity, why did you use ATF instead of the .... 90w72 or something like that. I only used ATF in transfer case and transmission. Very nice work though and thanks for sharing.
Because in the documentation I found information that the same ATF can be used as in the gearbox
Did you drain ATF to rear differential?
very nice job. Do you have any idea what could cause continue high low pitch noise under only deceleration when let go of the throttle before I go mad and dissemble all the rear end?
Vehicle is a Merce Sprinter 1998 and it was even there when newly bought at the end of '97 (Original service back then serviced it when it's 4 month old but never found a thing and the sound is there even after 20 years of usage)
the noise is from 1998 and nobody found the cause? I understand that the noise is coming from the back of the car?
@@mymercrepairs1097 yep it's definitely the diff.
It was the third Merc Sprinter in the country and no one had an idea of it till 2000's and then it was too late.
The reason I'm complaining about it is increased amount of noise under decel.
@@SweetyVoltyy Hmmm. I admit it's an interesting case. Most often, in the case of the drive on the rear axle, the shaft support is to blame, but in this case I doubt it would be a problem because the damaged support would not last for so many years. In my opinion, the rear differential will be to blame, one of the bearings is damaged, I think it may be the input bearing. Start by changing the oil in the differential, pay attention to its color, take pictures of the oil and send it so that I can also assess the condition of the old oil.
If the noise increases after replacement, it is 100% to blame for the problem with the differential
1990 300 CE 210mm 3.27 differential. Do you think it will fit in another car with a 210mm differential. It’s a 2006 Chrysler 300C
Woah, so you're saying the carrier bearings in the rear diff are the same as the ones in the front diff?
What the heck? Were the bearings you removed KLM and you replaced them with LM?
The front diff is notorious for failing with the same KLM503349/KLM503311 bearing, the rear is not usually an issue.
The KLM503349 is made in Poland and seems to fail frequently in the front.
Could the increased oil capacity of the rear diff be helping?
I never heard of the rear using the same bearings. You didn't make a typo or anything, did you? Just askin'. :-)
What about the pinion? What are part numbers? And yes, per the dealer and lube info supplied from MB, diff is supposed to have GL5 gear oil, not tranny fluid. Transfer case does call for ATF134.
And btw, nice video! Thanks for taking the time.
In the 11: 06s video I showed the original bearing numbers that were in the rear differential. I used Timken bearings numbered KLM503311 KLM503349 it is the same bearing

Dimensions are important
After the change, they work flawlessly so far :)
The oil I used is 75w85 as recommended by Mercedes but a lot depends on the climate in which the vehicle is used. countries with hot climate better use 80w140 cold countries 75w85 countries with moderate climate 75w90. ( I changed the oil in my Mercedes to 75w90 ).
It is true that the rear differential breaks less often and the front differential is more problematic. For me, the damage was a consequence of the stupidity of the previous owner who drove hard despite the problems with Lock UP and destroyed almost the entire drive in the car :(
Regular servicing and oil change is also important Polish bearings are not the cause of the problem, in my opinion, they are simply too small for the loads they carry, especially on the front axle of the vehicle, it is a design error or intentional operation of the Mercedes :-/ The front differential has a slightly design other structures than the rear one which may have an impact on the worse lubrication in bends. It is also affected by other momentary forces during driving, the load is primarily on the rear axle and the front axle is temporarily loaded, often very quickly when the rear loses its grip, which is not good for the bearing strength.
The oil in the central differential depends on the type, it is different in the version with the off road package and different in the ordinary transfer case
But the truth is that everyone will be better than the old, never replaced factory oil :(
Why not replacing shaft seal?? Thanks anyway good job
Great video ! I would also have a question please, is the differential from w251 also suitable for ML 280, year 2006? Thanks !I guess the differential is the problem because sometimes when I put the brake there is a shock in the back, I checked all the joints and they are ok.
The differentials are the same on w164 w251 and x164 but they differ depending on engine and model in gear ratio.
@@mymercrepairs1097 My car is a Mercedes Ml 280, 140kw, 190hp, can you help me tell me what kind of differential should I buy? Thank you
@@msmitanu5896 I will try but I will need your car vin
@@mymercrepairs1097 The win is WDC1641201A132240. Thank you very much for your time!
@@msmitanu5896 Ok, I found the differential ratio is 3.45 but after dismantling you need to make sure that it is the same. alternatively you can check the configuration in the engine ECU
How many miles have had the car ? Good job my friend 😉😉
143 thousand miles
Loved the Music. Can you use ATF in you Diff you can. Will it last? Probably not. I did this once on the advice of a transmission shop and Never again because 6 months later I needed a New Rear Diff. Now I use Valvoline SYNpower. Full Synthetic 75W-140 Gear Oil. This is what you want to use! Bottle also say's "Limited Slip" Change out that fluid ASAP. Running Strong in My GL450 and all my vehicles. I never had a Problem since! Hopefully this helps and you see this in time. Thank you.
If your differential died after changing the oil, it means that its condition was already very bad fresh clean oil only showed his condition and did not affect its destruction, changing to 75w140 can help because it is very thick when warmed up and masks the noise of the bearings but it causes an increase in fuel consumption
There was nothing wrong with the rear it was in excellent condition. I should have not even Changed it. ATF could not handle the "Shear" of the gears. Anyway thanks for the video and good luck.
@@tomb375 It's hard for me to say in what condition your differential was in the one I was repairing, the oil was never changed, but it was completely damaged, I changed ATF many times in gearboxes and differentials, usually to the one recommended by the manufacturer and they worked for years without problems
Backlash procedure and measuring shims should also be included in differential videos. good try though.
Mam podobne luzy w swoim w164. Stukanie przy dodawaniu i odpuszczaniu gazu to może być tylny dyfer? Co prawda nie huczy. Mam wersję z elektryczną blokadą (off road) więc to chyba inny niż na filmie.
Możliwość jest kilka po pierwsze sprawdź czy nie masz luźnego silnika zdaza sie ze pękają gumy kołyski lub poduszki silnika sprawdzisz to otwierając maske ktoś patrzy na silnik a ty ruszasz z wciśniętym hamulcem jeżeli chodzi o napęd to są 3 Możliwość przedni dyferencjał tylny dyferencjał i środkowy. Lub tak jak u mnie wszystkie na raz :( pakiet Offroad u ciebie faktycznie nieco sie różni od mojego ale zasad jest ta sama ty masz tylko dodatkową przekładnie redukcyjną sprawdź czy łańcuch nie jest już luźny
Poprawka dodatkowa przekładnia jest w środkowym dyferencjale a z tyłu jest blokada tak jak piszesz mój błąd cały czas chodziła mi po głowie skrzynia rozdzielcza :D a co do testów to możesz sprawdzić cały napęd tak jak ja wlacz nagrywanie na telefonie połóż go na asfalcie po środku samochodu i powoli przejeżdżaj nad nim i ruszaj z hamulcem tak by nagrać cały napęd od przodu do tyłu ważne napędy muszą być dobrze rozgrzane ! Potem sprawdzić czy gdzieś niema przeskoków albo nierównomiernego obrotu wałów np najpierw łapie przedni potem tylny wał jak masz możliwość wejścia pod samochód sprawdzi tez mocowanie skrzynia biegów ma jedną poduszkę jeżeli jest zerwana tez da identyczny efekt
@@mymercrepairs1097 Kiedyś byłem u dwóch mechaników na podnośniku najazdowym. Jeden twierdził że to reduktor a innym razem drugi mechanik że luz w tylnym dyfrze. Poza tym boją się dotykać do takich rzeczy jak dyfry i reduktory. Z jakiej części Polski kolego jesteś ? Jakbym nie miał do Ciebie daleko to może bym przyjechał na diagnozę :)
@@bogunow lata posiadania Mercedesa nauczyły mnie jednego mechanicy nie mają pojęcia jak naprawiać takie auta :( popatrz na mój film i powiedz co jest trudnego w naprawie tego dyferencjału? Jestem z Krakowa
Hi, do you know the pinion bearing numbers? Or where to find the information. The Mercedes does not give the information... Thanks!
I used many sources in my search for information. I bought a ready-made kit for Mercedes. Unfortunately, I don't remember the pinion number, I saw it somewhere but I don't remember where. If you are not in a hurry, I can remove the bearing from my old differential and check its number, but it's only in 2-3 days because I have a job now
@@mymercrepairs1097 Hi, now hurry. Mercedes in Europe do not sell bearings only seelings...
@@tuomopimia8362 I know that Mercedes does not sell bearings, but the whole differential at a very high price. Tomorrow I will try to unscrew the attack shaft and check the bearing number, but I have the usual differential without the offroad package, I do not know if these bearings will be the same
Very professional, clean and dedicated! Are you Russian?
I'm Polish
Witam. Mam identyczny klik w moim CLS 218. Mechanicy wymienili mi już tuleje tylnej belki krzyżak wału poduszka skrzyni półosie a dalej stuka przy dodawaniu i odpuszczaniu gazu oraz zmianie biegów. Czyżby to również był dojechany dyferencjal. Nie mam już pomysłów.
what about balancing/centering shaft with new diff?!
replacement of the differential does not require centering or balancing the shaft, but shaft control and balancing is a good practice mine was inspected earlier after replacing the damaged differential all vibrations and noise disappeared
Write bearings part number
Який момент затяжки болков ?
Niezły film! Nie myslałeś aby tylny dyferencjał uzbroić w torsen ? Przy skręcaniu nie użyłeś kleju do gwintów... nie trzeba ? ok. 18:00 ruda jak na większości MB niestety...
Myślałem o torsenie ale wymagało by to sporo przeróbek są oryginalne z blokadą mechaniczną od wersji offroad ale są ciężko dostępne i kosmicznie drogie do tego trzeba nieco modyfikować elektronikę. Kleju nie trzeba używać sylikon zawsze dostaje się do gwintu i klei śruby nie zdążyło mi się żeby jaka kolwiek sie odkręciła
@@mymercrepairs1097 aaa okay, dzięki
А чому Ви не наносите антіоткрутку на болт ?
I have ML63 AMG and when is running downhill without any gass on gear .. o herd from back from time to time RRRRRRR...
How to diagnose the rear dif?
Thank You.
Change the oil in the differential and check its condition if there are a lot of metal filings in it, it is most likely damaged
When i check under the car i can litlle move the shaft but litlle.. is this normal?
@@ank71 Yes it is normal for the shaft to be able to move back and forth and up and down
@@mymercrepairs1097 Hey.
I have one question.. i need to change my Sterring Knuckle. And im not sure is it the same from W164 420CDI and W164 AMG.?
@@ank71 It will almost certainly fit, but to be sure, compare the part number with your car
