Putting new gears in a 9 inch. I am going to use shims between the pinion bearings instead of the crush sleeve. I would preload the crush sleeve based on pinion nut torque and rotational force of pinion torque.

I imagine with shims I'll still set this up using rotational torque, but how do I know how thick of a stack of shims to use? How do you use the shims?

we usually make a spacer to replace the crush sleeve( make it like .030 to .040 shorter than the crush sleeve) then shim from there. go with the same rolling torque as with the crush sleeve, a little less if you're installing used bearings. everything should always be adjusted a little "free-er" with used bearings

Another option is to put it together with a crush sleeve. set everything up then take it apart and have a spacer made to the same dims as the crush sleeve. Or at least use the crush sleeve to set up your spacer/shim pack length.
