I guess there's a chance you could have bent the yoke...
And for all the rookie gear installers, the easiest way to remove a pinion yoke
is push the pinion out once the carrier is removed.
If you take a look most pinion gears have a dimple in the center,
leave the nut on a bit as not to wreck the threads on the pinion.
It's nice to have a air hammer but a good sized punch works with a hammer.
When setting pinion depth you may need to pull the yoke 2-3....times.
And if you dont have a air hammer, a 3rd hand will come in handy or the pinion
may go for a flight with a crash landing.
So dont beat on the yoke, push the pinion out!
And oh, put a little oil on the pinion splines so the yoke will slide off & on easier while setting depth.
