What to know about lubricating the doors:
Doors let the driver and passengers to enter and exit the vehicle. They are usually supported by their hinge at one end and a latch at the other end. Some doors work on a track, allowing the door to slide open rather than swing. When a door is open, the full weight of the door, window, and locking mechanism is supported only by the hinge.
Facts to Note:
Lubricating the door will permit the hinge or track to operate more smoothly, but will not repair a damaged component.
Doors that shake or sag will need more than lubrication to work properly again.
Poorly lubricated doors may be harder to open and may be noisy as well.
How to Fix:
The vehicle doors, hood, and trunk are opened
The hinges and sliders along with the latches are cleaned of old dried up grease
The hinges and sliders along with the latches are lubricated with lithium lube
The door is opened and closed several times to spread out the lubricant and more lube applied as needed to fully lube doors
The excess grease cleaned up and all doors are closed
When doors show the first signal of excess friction when opening or closing, an appropriate lube should be applied to keep it functioning correctly and smoothly, preventing excess wear and tear. When the lubricant on the doors begins to be less in effect, it is a good indicator that lubricated or greased components elsewhere on the vehicle may be experiencing excess friction as well. When the door hinges or tracks are being inspected and lubricated, it is a good idea to inspect and lubricate other moving parts on the outside of the vehicle such as the hinges connected to the hood or trunk lid. Extreme weather conditions will cause the lubricant on hinges and joints to age prematurely as well, so those living in very hot or very cold conditions will need to service these parts more often.
Common symptoms indicating you may need to lubricate the doors:
Loud squeaking when opening or closing doors
Door movement is less smooth than it once was
Door gets jammed while opening or closing
Importance of this service:
This service is to some extent important for doors that swing open on hinges. Doors will get noisy and become harder to open and close as time goes on if they are not properly lubricated, but as long as they function properly they will still serve their purpose. This service is more essential for doors on tracks. These doors have more parts that need to be lubricated frequently and are significantly more prone to jamming if this is not done. This could also cause the door to close improperly, permitting the door to open while the vehicle is in motion. Proper maintenance of hinges and tracks will prevent expensive repairs in the future.
