Yes, you can do as you said in your post, but, the pinion nut MUST be in the exact place it was before you removed it when your done. It sets the pre-tension and crush washer for the pinion.

Or just buy a new stake nut since technically they can't be re-torqued.

The reason is because the collar is suppose to be seated without the carrier inside the rear diff by the amount of rotational drag.
Now as easier way is to mark the nut and yoke. Then, count the number of turns it took to remove the nut. Replace the seal. Re-install the nut to the position in which you took it from. Tighten it a little bit (less than 1/8 of a turn) past the original markings. This is a better way to do things so to keep near the same drag as before. But the true way is to remove the entire rear diff guts and start from scratch! Of course i wouldn't go that route even if it was my own truck. i would just mark the nut, count the turns and be on my way. No actual need for torquing at that point.
The crush collar tightening is one of the most important things to do in a rear diff to keep everything harmonized.
