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.

Re: Pinion oil seal?

I would say that even a beginner mechanic can replace that seal. The hardest part is removing the pinion yoke. Then you just pry out the old seal, and pound in the new one (with a rubber hammer). Easy fix...... really.

Re: Pinion oil seal?

BIG mistake if you don't do this right. If it is a model 20 before you remove anything use an inch lbs. torque wrench to see how much you need to rotate the pinion. Then remove the nut, yoke and seal. Replace the seal, yoke and nut, and torque to 5 INCH LBS. more than the original reading. Any more and you will damage the crush sleave, then have fun resetting the pinion depth!

How is the pinion removed? Just something like a handle that screws into the bolt holes and a good bit o' pullin'?

Re: Pinion oil seal?

A puller is easiest if it has been on there awhile. One other thing I almost forgot, very important, when you put the pinion back on make sure it is EXACTLY in the same position as when you took it off, otherwise you may end up with vibration.
