Needs to be filled with the car level.
Otherwise you'll overfill the diff, and that newly fitted seal will start leaking again VERY soon.
Thanks mate

. I read in the maint section that you jack up one side but i'm gonna be checking it again in few days and see if its leaking again or not. If its not then i'm hoping its jobs a good'en then as i made sure i did not go mad and as soon as it started to leak out of the plug i stopped. Am i right in thinking all it does is stop oil from leaking out and crap from getting in???
