question about pinion nut

[PeteyAce]

My pinion nut gets stuck once the top of the nut meets the top of the thread of the pinion gear

I had tightened it with a racthet the more i went down the hard it was to turn and when i took off the nut there were indentations right where the nut got stuck

this is what i guess is stopping it from going down, but is my pinion nut bad? or is it suppose to get tight like that?(i tired to turn in down on both new pinon and old pinion gear get stuck at same point)

You should be able to bottom it out with a rachet. Time for a new nut.....

The pinion nut has the factory thread locker substance on the threads that help to stop the bolt from ever backing off. Usually it requires some effort to remove or tighten the pinion nut. As long as the threads are not damaged, the nut is fine. But if you still worried, buy a new pinion nut, its not expensive.

wear the marks are on up above the metal is actually bent a little causing the bare metal to show, i think it might be the nut, but i had another one nut with the same exact problem.
