Leaking pinion seal
I am really bummed out. My pinion seal is leaking after only about 150 miles. After months rebuilding/ restoring TA, suspension and differential. Can this be replaced with diff still in the car?

Yes, it can be changed without pulling the rear end but its obviously more difficult. Are you absolutely sure its the pinion seal that is leaking? I'm just wondering because you took a picture of the right side yoke.
When you had everything apart did you do any work on the rear end like changing seals or anything else?

I would be hesitant to do it, but :
- mark pinion nut location on the shaft.
- count the amount of threads above the nut
- measure the amount of rotating torque.
- pull it.
- replace seal.
- torque it to its previous setting, minimum to the mark + amount of threads you counted.
Never done it but that's how I would do it.
Others may have better advice.
Good luck.
PS : I'm not so sure this can be easily done with the diff in the car as the pinion nut is not easily reached that way.

We used a long extension and hammer. But you need another person to hold the extension as you hammer.
Use sealer on the pinion shaft, lube can migrate down the threads
