I’ve read 2 Q&A’s about piñon shaft oil seal and gaskets - but it’s not clear that both are required with a new style piñon oil seal. Wish it said that the gasket was required when I bought the seal. And what about the oil slinger? Where does that go

Willys Jeep Parts Tech:
Alot of people do without the gasket since the seals are now neoprene but they are originally there.

I have a 1946 willys cj2a, I have replaced the pinion shaft oil seal twice, but it still leakes. do I need to replace the gasket also? and if so where does it go?

Willys Tech:
It is probably your yoke that has a wear pattern cut into it. That is probably the problem. I would check it.

For the Pinion Shaft, shouldn't there be a complete Oil Seal and not just the gasket ?

Willys Tech:
639265 is the part number for the pinion shaft oil seal
