8.8 swap

on Salisbury type differentials ,,,, the carrier should have to be pried out of the case -- this shows that preload on the carrier bearings is still present -- usually on higher mileage axles the carrier can be easily lifted out of the case due to bearing wear which decreases the preload on the bearings , you will also see that the carrier preload shims will be worn as well -- when you rebuild the diff with new bearings /gears this preload must be re-established so the carrier/gear will run true to the pinion gear and have no side to side movement.
