Hello,

Drained the fluid then fastened plug. Opposite that is the overflow plug I left open. On the passenger side there are two m6 Allen head plugs. I removed the lower one filled until fluid started coming out then closed. Removed the upper one filled until fluid started coming out then closed. In all this time no fluid came out of the overflow plug the car was level. It took about 1-1/2 quarts.

Yep, that sounds correct. Here are the instructions on how to service the front and rear differentials with the fluid type and capacities. Check out the images (below). Let us know if you need anything else.

My question was how come the fluid did not come out of the overfill plug hole where it’s supposed to come out.
