Hello,

Does anyone know the OEM part numbers for differential oil and transfer case oil part number?

Thanks for your help.

you mean the 75-90 gear oil?

Is there only one? I have a AWD and I believe the manual says both need to be changed at 60k I might be mistaking.

Thanks for your help

Just get some Mobil 1 synthetic 75w-90 gear oil at any auto parts store. That is probably what they used at the factory as Toyota motor oils are made by Exxon/Mobil. That is what I used when I changed my RX differential and transfer case fluids. Get 2 bottles, you may have some left over. Great stuff. However any synthetic 75w-90 gear oil will work just fine.

Always open the fill plug first because if you drain it first and then cannot open the fill plug, you will be in a heap of trouble!

Just pick your favourite oil manufacturer. Toyota don't manufacture lubricants, so any oil manufacturer will do, just as long as it meets the spec. Your choices could be Mobil1, RedLine, RoyalPurple, etc.
