The proper way to do it is to have a beam type torque wrench that goes in small increments, 1/4 or 3/8" drive, so that you can read 5 inch pounds of rotating torque. To get an accurate reading make sure that the pinion races are seated ALL the way and the bearings are lubes with oil.
First you tighten the pinion nut so that the slack in the pinion is just taken up. Then tighten the nut a little at a time, measuring the rotating torque after each tightening, until you get the 5 inch pounds of rotating torque. You are then done. The crush sleeve is now "crushed" and has the proper load on the pinion bearings.
