Inner seal

So, I notice that there was some fluid coming out of my passenger side axle and onto my knuckle.
I had decided I was going to replace the inner seal, but also while I was at it, I might as well replaced some bearings. I went to NAPA and found out that my bearings are all within a closed unit. He gave two seals, and when He gave them to me he told me which ones were which.
My question is simple: where the hell does that inner seal go? I have a Dana 30 front end on a 2000 Jeep Wrangler Sport. I think that it goes in the axle tube, but that it sits down the shaft next to the gears.
Does anybody know if this is true? And if so, what do I do to gain access to that area without messing my differential up?
Anybody?

The inner seal is typically located at the tubes near the differential, which I believe requires removing the carrier from the diffs.

The Hub Assembly (Unit Bearing) is an easy replacement process.

Doesn't the inner axle seal needs a special tool as well. I need to do mine to and considering the dealership and being broke again.

Well, I tore into it. After a friend came over who knows a little something about Jeeps, we came to the conclusion that a gradual leak is of less concern than taking the bearings out. I just don't have the time to mess with it, only to find myself in a bigger pickle than I was in to begin with.
So, I put it back together. I am a little concerned about how I put my axle shafts back in. I didn't pay much attention to thier original positiion, so I hope that doesn't cause excessive vibration. I took it for a drive in some soft mud above my house, and it seemed to do alright. I still have a pinion seal that's leaking as well. I am not looking forward to changing that.

you can only replace the inner sealswhenyou remove the diff.
you can install the new seals with a fitting metal tube and with a hammer. I did it today and it worked very good.

The pinion seal is pretty easy, hardest part is getting the pinion nut loose. Lot easier than the axle seals

Are the seals for a 95 and earlier, different than that of a 2000 Dana 30?
