assembly into the steering knuckle. The FSM has you use 3 different drifts to press out/in the seals, axel and bearing assembly from the steering knuckle. The nut that hold on the axle on the steering knuckle needs to be replaced as it has a flange that gets bent over to secure the nut from rotating. The retaining ring can be reused. Good luck....& try to enjoy ZCON!!
