For your car doors to work well, you have to perform some routine maintenance especially on the hinges. Most of the time, car owners tend to overlook and put off these maintenance regimens until they notice some irregularities in the way the door operates. It's a good thing that door hinge maintenance isn't that taxing and will just require a few minutes of your time.
Among the common maintenance routines your door hinges require are lubrication and bushing replacement. Here are the steps on how to carry out these procedures:
Greasing the hinges
What you'll need:
- Grease gun
- Spray lubricant
- White lithium grease
Step 1: Prepare the door and the vehicle.
Park the vehicle in a well-lit area where you can work comfortably. Open the car door and rid the hinges of mud and dirt buildup.
Step 2: Spoon-fill the gun with white lithium grease.
The right way to do this is to take the cap off the gun's grease tube and use the spoon to fill the gun with grease. Put back the cap and try to pump the trigger for several times until the grease starts to spurt out of the gun's nozzle.
Step 3: Spray grease into the hinges.
Aim the tip of the gun's nozzle into the space in between the hinge pin and the door hinge on the inside part of the door frame. Pull the trigger of the grease gun a few times to drive and spray grease into the area.
Step 4: Test the door.
Make the grease penetrate well into the hinge by closing and opening the door for a number of times. If the door now operates quietly and smoothly, move on to the next door.
Replacing a door hinge bushing
What you'll need:
- Soft cloth
- Floor jack
Step 1: Open the door of the vehicle and position the floor jack under the door's center. Raise the jack until it comes in contact with the bottom of the door.
Tip: A jack that doesn't have a rubber cover on its arm should be covered with something soft like a cloth or foam to prevent its surface from scratching the door.
Step 2: Use the hammer and the drift to force the lower pin out of the door hinge. Do this by hitting the bottom of the pin so it moves upward. Do the same to drive the upper pin out.
Tip: While doing this step, ask someone to hold the door so it won't tip off the jack when the pins are released.
Step 3: With the drift, force the bushings out of each door hinge.
Step 4: Slot in the new bushings and line up the hinge on top of the frame hinge that houses the bushings. Make sure the holes are aligned before inserting the pins.
Tip: It would be easier if there's someone to assist you in lining up the door hinges.
Step 5: Use the drift again to slide in the pins. Test the door and see if it now works well.
