I forgot to mention one thing... When doing the final-install of the pinion nut, I filled the cavity between the pinion splines and the pinion nut and washer with RTV sealant. It might not be needed. But this is one spot on the pinion that doesn't have a seal and could be a point of leakage. This is a trick I picked up from watching how-to-build-a-diff videos on YouTube...
