Pinion oil seal?
I had occasion today to have to replace my U-joints on the rear drive shat. When I was working on the pinion yolk on my AMC 20, I noticed a small trickle of oil. It is coming from the thing that holds the pinion yolk in place.
Is this an extremely bad thing, or is a little okay. Can I fix it? I have never done anything major, no clutches or anything like that, just basic stuff.
I know that axles are very important to keep in good shape, and I don't know anything other than the most basic things about axles.
Thank you for any help.
