dont worry about the little love tap with the hammer. i have had to put carriers in using the same method. it is the relationship between ring and pinion that is the main concern. you shouldnt have to remove the carrier to install an easz-locker as it is a lunch box stlye lockers, replacing only the carrier gears.( axle gears and spider gears). hope this helps ya a little. i am sure someone else can provide anwsers to your ??? soon enough.
