Pinion yoke on F10B R&R

[Geargrinder]

I busted the front U-joint, and it tolk out the yoke 2 I have a spair, but I'm gessing that when I do this I will be messing with the pinion pre-load, right?
So how do I replace it and get the preload right?

As I see it, there is no real "right" way to do it, short of pretending like you are doing a complete gear setup, with pinion preload being measured. (think thats the right term)

I've done a few 10 bolt rears, I take a good sized breaker bar, (while under the truck) and tighten it up as much as I can. So far I must be lucky, I've never had a problem doing this. It certainly isn't "the right way" to do it, but when the nut comes loose, and you don't have the tools to set itup correctly, you do what you have to.

You'r right, just measure the pre-load before you do anything. Then
measure the pre-load after, you replace the yoke,seal, and nut.
Simple

What do I use? Do I just put a dial indicator on it and mesure end play? Or do I mesure gear lash? Or can I just feel how it spins and try to get it as close as poss to that same feeling?

Sorry thought you know pre-load. Its a rotating torque that you need to measrue, use a torque whench to rotate the pinion gear/nut.
You will be measuring a very small amount, you torque whench
needs to read inch/onces, not foot/pounds.
Good luck
