is needed usually from worn out springs or lack of maintaining the lubrication for the wheels. LUBRICATE MOVING PARTS The moving parts of a garage door require periodic lubrication. Use an aerosol spray lubricant and wand to clean and lubricate all these moving pieces: Combination hinge and rollers: Apply lubricant to the roller and the hinge to which the roller is attached (at either side of the door, between each pair of panels). Use lubricant sparingly; too much attracts dirt that eventually will gum up the works. Hinges in the field or center of the door panels: The hinges that hold the center of the door panels together don’t have a roller. Apply lubricant to these hinges and then operate the door several times to distribute it evenly. Lock mechanism on the door: Spray lubricant into the keyhole and work the key several times to distribute it evenly. Lubricate the pair of locking latches at each side of a manual door.
