96 Dakota 318 4x4. I may need to change the yoke. Does this diff use a crush sleeve or would I be able to simply remove and replace the yoke?

Thanks

The 8.25 differential uses a crush sleeve to set pinion preload. If you're careful when removing the old companion flange [after checking the rotating torque of the assembly] & replacing it with a new one [companion flange/bellville washer/pinion nut] tightened to the same rotating torque as before, you should be good to go!

use your torque wrench to take off the pinion nut .....so you know the value....

You need to add 5 in lbs. of torque to whatever you recorded. Don't worry about the torque to remove the nut. The crush sleeve provides the bearing preload, and has to be "reloaded" to apply preload, which is why you add 5 in/lbs. of rotating torque.

This is false as to resetting the torque going back together. The break away torque value will always be high--usually higher than what the nut is torqued at. This is why they are set up with a turning torque value---and that value vaires between new bearings and used bearings (see sevice manual for specs for the application).

Also, most torque wrenches of any real value will not be accurate in reverse. Some upper end ones do not even have a reverse lever on them (Snap on, Mac Tools). They make a different wrench for torqing in reverse--or both ways (usually a fixed non racheting head).
