First and foremost, we disassembled the brakes and brake brackets and gently pulled the axles out. We then could unbolt the main caps, and gently pry the spool assembly out of the 12-bolt housing. Next, we can unbolt the pinion and pull it out. Before taking another step, we made sure that both pinion bearings were in good shape. We checked the gear oil that came out for any shards or metal and once we were satisfied it was OK, we continued the installation.
