Outer Limits 4x4 Board

hey guys
just got my new pinion seal in. just a quick question. where do i fill my diff from and how do i tell the height? is it similar to a dirtbikes gearbox overflow screw as in when the oil leaks out of a hole its full?
cheers

unto the filler plug. its about halfway up the pumpkin on the housing side. fill it up until oil comes out.

easy

thanks mate. was thinking that but didnt wan over or underfill it and cook my diff. my only drive at the moment. have to gentle even if its no fun
cheers
