Re: Replaced pinion seal but did I do it right?

No, you have to drive it out.

When reinstalling you have to use the yoke and nut to drive the front bearing back on the gear. It doesn't just slip on.

No disrespect meant. I was a transmission man at GM dealers for 15 years before I retired to teach auto repair.
This is correct , The bearing will not come out without driving the pinion to the rear . This is why when setting up a gear most will hone out the small bearing to easily remove it and not have to hammer it out . Some will also hone a new large bearing as well to to make it easy to change shims when setting it up .

You can not get the small bearing out with a assembled differential .
