Q: How to maintain and lubricate Door Hinge, Door Latch Assembly, Hood Hinge, Hood Latch, Trunk Latch on Lincoln Mark VII?
A: First of all, the hinges as well as latch assemblies of the doors, hood, and trunk should be lubed with a few drops of light oil or lock lubricant once every 3000 miles or three months. The door latch strikers also require some grease to minimize wear and enhance free movement. Therefore, it is important to use a spray-on graphite lubricant to oil the door and trunk locks.
