Who can guess why this pinion seal is leaking???

Cracked!

Finally got around to tearing it down to repair the leak.
It's exactly as I predicted it was.
The 4.09 gear set has a smaller 26 spline pinion shaft and yoke.
They installed a stock dana 44 seal that was obviously too large to seal properly and assumed it would be OK riding on the dust cap.

***EDIT***
Found the correct seal (Spicer 44895)
