swapping front axle yokes from a 93 to a 96, whats the torque?

so im swapping over to 3.73 gears on my 93zj so i had to find a front and rear diff, well the front diff i got was from a 96 and they changes the yoke style from the u joint style to the cv style, so im just going to swap the yokes from one to another, so what is the torque going to be on the nut because doesn't that change the bearing preload the more its torqed?

The way that the yoke is correctly tightened is to measure the bearing preload. There is not a set torque for the yoke nut itself.

Unless you don't want to keep that gear set for long.

Remove everything from the axle including carrier. Mark the bearing caps for which side they go on.
Using a 0-75 or 100inlb torque wrench(any digital, dial or beam inlb wrench with single inlb markings will do) measure the torque required to rotate the pinion and record it.
Remove the pinion nut recording the torque required to break it free. You'll need a dial, or beam 250 ftlb wrench for that.
Put the new yoke and nut on tightened to 5ftlbs more than the previous nut and check rotating torque. Increase in 5ftlb increments till you get in spec without exceeding 275 ftlbs.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.
