I have the same leak I believe. It’s either the pinion shaft or one of the two hard lines below it. I used Lucas oil stop leak to see if it will help, but I’m not holding my breath it will.

Couple of questions I was hoping you or someone else could please answer.

1. Did you find instructions on how to replace the pinion shaft seal?
UPDATE: I found an answer to this one via YouTube. I am guessing the process is the same as this video?


2. For the leak at the hard line, did you use o rings from the Amazon kit linked earlier in this thread or were you able to find a part number?
