Whenever you take care of chassis greasing, it is also advised that you walk around the vehicle and give attention to a number of other surfaces which require a variety of lubrication/protection.
Lubricate the door and tailgate hinges, door locks, door latches, and the hood latch when they become noisy or difficult to operate. A high quality polyethylene grease should be used as a lubricant.
HOOD/DOOR LATCH & HINGES
Wipe clean any exposed surfaces of the door hatches and hinges, hood latch, liftgate hinges and latches. Then, treat the surfaces using a multi-purpose grease spray that meets Ford's ESB-M1C193-A specification.
These should be treated with Ford Lock Lubricant, part no. D0AZ-19587-AA or equivalent. Consult your local parts supplier for equivalent lubricants.
Spray the door weatherstripping using a silicone lubricant to help preserve the rubber.
