Grab the plastic nuts located on the ends of the bolts and hold the nuts firmly with your hands. Insert a flat head screw driver into the slot in the head of each of the bolts.
Hold the bolts in place with the screwdriver as you turn the plastic nuts on the underside of the back of the toilet’s bowl. Place the plastic nuts in a safe location and pull up on the back of the toilet’s seat.
Spray penetrating lubricant in the threads of the plastic bolt If the nut does not unthread easily. Wait at least 5 minutes before trying to unthread the nut from the bolt, allowing the lubricant to work its way into the space between the nut and the bolt.
