I am not trying to write a how to thread here, but instead I am publishing the notes I took getting ready to do this repair. I hope this serves as a reference to others to help jump start their project.

Here is a list of the threads about replacing pinon seals and placed them here to help other find them. I have also added other links with good info too. I hope this helps someone.
