Q: How to maintenance the hinge and latch on Ford Thunderbird?
A: At least once after 3000 miles or three months, should you put a few drops of light oil or lock lubricant on the hinges as well as latch assemblies of the doors, hood and trunk. Additionally, there should be a thin coat of grease applied to the door latch strikers to minimize the wearing process and guarantee easy motion. You can also use spray-on graphite lubricant to oil door and truck locks.
