Front diff leak

My 9.25Ē AAM front diff is leaking from the pinion seal. Should I do the whole kit with both seals or just the outside one? I have done the outside one my self on the rear of another truck and it went fine, idk how to do the inside one bit Iím sure I can learn.

My rear is leaking slowly still, bought the kit a while back and still havenít made time. The front diff started leaking but itís worse and dripping so I need to do them both now I guess. Ugh.

Best to do both but look up how to do the inside one and you may not feel like tackling it. If that is the case you can probably get away with just doing the outside.

I replaced the outside one on my pickup about 10k miles ago. Still not leaking. I used a NAPA seal.
