Nissan 82421-1KA0A Front Door Hinge Assembly

Work around the vehicle, lubricating the hinges of the bonnet, doors, and tailgate or boot lid with a light machine oil. Lightly lubricate the bonnet release mechanism and the exposed sections of the inner cable with a smear of grease, and similarly lubricate the tailgate and fuel filler flap release mechanisms where accessible. Carefully check the security and operation of all hinges, latches, and locks, adjusting them as needed, and verify the operation of the central locking system. Additionally, assess the condition and operation of the tailgate struts, renewing them if either is leaking or unable to support the tailgate securely when raised.

Every 3000 miles of operation or three months, the hinges and latch assemblies of the doors, hood, and trunk should be coated with a few drops of light oil or lock lubricant. Also, the lengthy components such as the door latch strikers should be greased to reduce wear and to ensure they slide smoothly. It is also important to spray in some graphite lubricant on the door and trunk locks to enhance their working.
