You don't. Mark the pinion nut position relative to the shaft and bring it back to the same position after changing the seal. If you go tighter, you will change the crush sleeve length and alter pinion gear preload.

And use permatex on the splines to prevent leakage.
Also note you don't drive the seal all the way home till it's flush in the housing, there's supposed to be a gap, you need to measure the depth of the seal bore and subtract that from the seal length to see how much it should stick out

You will find it very difficult to install the new seal if you are replacing it on the car. I tried a number of times without any luck so I ended up building a tool which consists of a pipe that fit the seal perfectly and extends about 18 inches so you get a good hit with a hammer. I have loaned out this tool to others and it really makes the job easier.
I also find a good impact removes the old nut easily. It is a job that can be done in about an hour.
To remove the rear universal use a couple of long extensions and a 7/16 socket. Again an impact really speeds this up.
I don't know if it is necessary or not but I also put a small amount of permatex on the seal OD.
If you find the seal does not fit well on the yoke you can get from Gary a nice sleeve that presses on the yoke and gives a better fit. It is pricy for this sleeve but it solves those leaking seal problems.

No seriously, you need to remove the carrier and torque the nut till the rotational drag is about 15 lbs.in, you need a dial type torquewrench for this
