Looks like it. Clean it up, spin it a bit, check it for leaks with your hand, and check it a few days later to see if there is more differential oil on the ground.
Does the fluid on the ground smell like diff. fluid?

My guess would be yes.

Yeah I know it's in there. I'm just kinda scared of rebuilding it when it has such close tolerances and I've never done it before.
Don't forget the crush tube. I got one bearing but I guess there are two in the pinion. I may just get new bearings and seals for the whole thing.

the manual states that you check the torque prior to removing the nut...
its pretty easy to do... just put a torque wrench on the nut as if you were tightening the nut... observe the torque spec when you see the nut begin to spin... it should be in the neighborhood of 94-130 ftlb

Look at pg 9-12, where it shows the guy taking off the axle nut with a flex beam torque wrench.

First of all, all you NEED to do is take the nut off and pull the pinion flange and seal out carefully of course. DONT SCRIBE THE NUT! I guarantee you will not reach the same torque as before using this method. Use the torque in the manual. It's not rocket science.
