    OUTPUT PLANET CARRIER SERVICE 3. To disassemble the primary planet carrier assembly, the steps are the same as for the output planet carrier assembly, except there is only one bearing for each gear. Also, the primary carrier has a thrust washer inside that can be removed after the planet gears are removed.
