Change out your Mercedes transfer case gear oil; This is important in keeping your Mercedes running smoothly and quietly as spent gear oil leads to premature parts break-down, excessive transfer gear noise and higher fuel consumption.

I just purchased 2017 Mercedes and your videos have been helpful. I am good self mechanic but no videos available. Thanks so much.

[@kvasir40]

Thank you for sharing this video. I was able to perform this fluid change following your precise instructions with few modifications as the HEX bits were different sizes for the fill and the drain (S550 W221), and this process saved me over the elevated quote my regular mechanic provided me with inflated fluid price and post-pandemic higher labor prices.

[@tonyatkinson-cp6ox]

Fantastic video ..at last someone who makes it all very clear to see and understand.. .go this fella he the man 11/10

[@chuckfinley3542]

If I ever remove the drain plug first and find that I can’t remove the fill plug, I simply turn the car over and fill the differential through the drain plug. It damages the car quite a bit, but at least I can drive it when I flip it back onto the wheels.

No reason to just automatically replace the drain bolt unless they are corrodedor otherwise damaged. If the old bolts were holding the fluid in then ts 99.9% chance they will continue to do so.

[@jbrooker78]

I have a 2007 GL 450 does it also take 1.3 quarts for each differential? Also I read online that you should torque the fill plugs to 50 nm?

[@vadneysean72]

Most are 50 nm. But ask mb as to the quantity or purchase the WIS for your vehicle to get exact specs.

I have an 09 ML350 4matic. Would you recommend only using the MB diff fluid, or would Mobil1 75w90 be sufficient?

[@gheorghebuzeiche4381]

75 w90 is a superior diff oil than MB spec ... 75w85 from MB is for a better fuel economy. Go with 75w90 from Mobil or any other well known brands..Motul, Amsoil, etc.

I have an 82 300SD and I hear whining from the back when I accelerate is that Normal (40 +mph) or the differential? Plus I’ll make sure to get some orange clean!

[@iRepairAutos]

that orange clean is golden... I'm not sure what sound you're hearing it could be a wheel bearing or two... You could (kinda risky) put the car in neutral at that speed and see if the noise goes away. If you do put it into neutral- bring the vehicle to a complete stop before you put it back into gear.

[@conormcgregor5460]

Could be your universal joint if you observe your drive shaft from transmission to rear differential grab it and try to turn it clockwise and counterclockwise. It won't turn unless the vehicle is in neutral but if you feel that it moves centimeters in either direction that could be the problem. A bad universal joint can make a whining scratching sound consecutively in drive or reverse at certain speed. And also if it clunks and the vehicle buckles when you engage it from reverse to drive and into park sometimes too it could be that transfer shafts universal joint worn out and needing replaced. They tend to wear as they take on different levels of torque and stress or heavy loads.
