2020 GLS450 gear oils
I am looking to replace the front and rear differential fluids, as well as the transfer case fluid for the vehicle. I am at 80K miles. I cant find anywhere what fluid to use. I can't even find the parts at MB dealerships online. Anyone who done this at dealership got a part number for the oil for me? thanks for the help.

Check Sheet 231.1 at https://operatingfluids.mercedes-ben...egory/gear-oil. You should find the gear oils appropriate for your vehicle in this first sheet. Then refer to the sheet that lists the approved gear oil brands.

I haven't done it yet myself but already got the fluids for everything with me, which will be replaced within this month.
Based on my research, both front and rear diff takes 75w85 but i opted for valvoline 75w90.
For the transfer case, MB 239.41.
Can't guarantee but that's what i've found so that's what i bought
