swapping out yokes

It will mess with your pinion bearing preload. Unless you know how to do it right, don't do it.

Best bet is to let someone with the right tools swap it out. I understand that it will cost more money to do so, but if you do it wrong it could cost you a whole lot more
Pinion bearing preload exists to make sure that the pinion bearings make full contact with their races.
Too little preload and the roller bearings will "skip" across the surface of the race and will wear out quickly and fail because all of the force is being applied to the small areas the roller bearing is contacting (think point load).
Too much preload makes too much friction which also leads to rapid pinion bearing failure.
The SF 14 bolt, like many differentials, uses a crush sleeve to set pinion bearing preload. Crush sleeves are one time use, period. If you need to replace the pinion seal or the yoke on a differential like this, you need to disassemble the entire differential and replace the crush sleeve. If you don't know how to do that, pay someone to do it or read here: http://pirate4x4.com/tech/billavista/Gear_Setup/
