first service changing all fluids, i pulled 330 ml out of the front differential as per manual, but i'm only able to get 200 ml back in, its just overflowing out , put the cap back on and drove it up and down the driveway in 4x4 took the cap off and it's still full can anyone enlighten me on what is going on??

No place that it can't get to inside so unless you pick that fill-side way up, not going to get that last 80ml in. I have always just filled it to the fill port and never had any issues....and the manuals aren't always 100% correct anyway.

well the mystery remains, i measured 330ml coming out, don't know where it came from . lol . i will keep an eye on it for awhile .

Are you using the fill plug on the drivers side or passenger side of the front differential? They look to be different heights. I don%u2019t know which on is correct.

I'm using the drivers side, wasn't aware there was 2. hmmmmm

My 2021 has the same one in your photo as well as one one the other side where the ring gear is. I haven’t gone into mine yet but the passenger side one is higher up.
