Pinion bearing preload is set with the flange nut, and the crush sleeve that was on the pinion shaft should be replaced. Any time the sleeve is crushed, it should be replaced. The actual spec on the pinion preload is 15-30 in lbs, and total assembly preload is usually 30-50 in lbs. To achieve preload, you are going to have to use some force when putting the differential case into the housing, that is correct.
