I’ve tried the search button. Couldn’t find a tutorial how to change it. My question is, are the both drain and fill screws on the differential or is on the drain on the diff but the fill is somewhere else?

How often should gear oil be changed by the way?

Drain bottom, fill on the side. You should fill it till it just starts dripping out the fill hole. I have no idea on intervals but i’d guess maybe every 50k or 2 years on a open diff. Maybe a little sooner on a limited slip rear.
