Q: How often should the hinges and latch assemblies on doors, hood, and trunk be lubricated on Nissan Quest?
A: Every 3,000 miles or every three months on the hinges and latch assemblies on the doors, Hood, and trunk a few drops of light oil or lock lubricant should be applied. Besides, pin tumblers and the door latch strikers should be greased lightly to reduce wear and make the operation smooth. Another area that should be considered serviceable for some lubrication is the door and trunk locks which should be given the spray-on graphite lubricant.
