Fill the small hole in the back of the dryer wall just above the metal bracket with high-temperature grease supplied with the rear drum bearing assembly kit. Fill the bearing hole on the back of the plastic replacement bearing with additional grease. Insert the ball bearing into the hole in the plastic bearing.
