Pinion Seal Question

IDing the leak before disassembly will be hard, since I have a dust cone attached to the yoke that covers the seal area. All I can say for sure is that the fluid is leaking from under that cone, so it's either the case-to-seal or seal-to-yoke. I would think if it were the splines that were leaking it would be running down from the from of the yoke by the nut.

I guess I can take it apart, re-check the yoke shaft surface, replace the seal, use shellac AND RTV the splines.

The 8.25 does use a crush sleeve, but I just put that in when I rebuilt it. I'll put in another if necessary, not really a big deal.

For my first ever axle rebuild, I'm pretty happy if a pinion leak is the worst thing I need to remedy. Otherwise the axle is hanging tough and not making any noise after the first few hundred miles.
