so after a day on the trails, I realized my pinion gear seal was leaking. I later opened up my diff and found muddy goop and i had changed my diff/tranny fluids 2 weeks prior. So to clean it out i decided to just empty the entire axle housing. and rebuild it using a rebuild kit. My only worry is, removing the pinion gear. does it have a certain way of going back in or is it more simple than I think. And also, any reccommendations on a quality rebuild kit? Any help is appreciated.
