Replace rollers on a sliding door in a few hours using a screwdriver, wooden block, rubber mallet, flat-head screwdriver and a paraffin wax block. To replace the rollers, locate two screws on each side at the bottom of a sliding door, twist the bottom screws counterclockwise, lift the door, and take it out. Put the door on the floor, and remove the other two screws at the bottom of the door.Continue Reading
Put a wooden block next to the bottom part of the door frame, and hit it lightly with a rubber mallet to take the frame off. Use a flat-head screwdriver to remove the old rollers from the bottom of the door. Bring the rollers with you when you purchase replacement rollers, and obtain rollers that are identical to the old ones. Put the new rollers in place at the bottom of the door, and put the bottom frame of the door back using the wood block and the rubber mallet. Place the four screws back at the bottom of the door, and secure them in place.
Loosen the bottom screws to raise the rollers, and carefully put the sliding door back in the doorway. Tighten the screws until the door is low enough to easily slide on the tracks. Sweep and vacuum the tracks before putting the door in if they are dirty.Learn more about Doors, Windows, & Locks
