What to know about lubricating the hood hinge:
The hood of a vehicle is a movable panel that shelters the engine. Hinges hold the hood to the rest of the vehicle. When the hood closes, the hinges make sure that the hood latches appropriately in the same position each time.
Facts to Note:
If the hood is not latching appropriately or the hood no longer lines up with the position of the latch, lubrication will not adequately fix the problem.
Greasing the hinges of the hood will make operation smoother and quieter, but will not fix any problems with the hinge’s location or physical damage.
How to Fix:
Apply grease to the hood hinge
Any issue with the hood or hood hinges should be addressed immediately to make sure proper operation and to stop expensive repairs in the future. By the time the lubricant or grease has worn out on the hood hinge to the point of needing replacement, it is likely that other moving points on the outside of the vehicle have suffered similar wear and tear. Check the latch mechanism of the hood, the hinges on the doors, and the hinges holding the trunk lid to the vehicle to assess if they could use lubrication as well. Surplus friction in hinges causes them to wear out prematurely and can cause real issues down the road.
Common symptoms indicating you may need to lubricate the hood hinge:
Difficulty opening or closing the hood
Squeaking noise when the hood is opened or closed
Multiple attempts needed to properly close the hood
Hood gets stuck when opening or closing
Importance of this service:
This service is moderately essential and is mostly done as preventative upkeep. In extreme situations, jammed or seized hood hinges can stop access to the engine compartment. If the issue is with the latching mechanism of the hood, then the service is more crucial. If the hood does not latch correctly, there is a possibility that it could open while the vehicle is in motion.
