If you are having difficulties opening or closing your car door, it may be time to replace the car door hinge assemblies. Besides squeaking and grinding, faulty car door hinges can cause a door to sag. This article will take you through the necessary steps for that fairly minor and inexpensive car repair.
Step 1 - Prepare
Whenever doing an automotive job, it's better to take precautions. Always wear safety glasses when using the metal punch. Gather the tools and materials listed above and park your car on a level surface. Apply the parking brake so the car will not roll during the repair process. Cover the jack support with an old towel to prevent damage to your car door. Open the door and support it with the hydraulic jack. Enlist the help of a friend to hold the car door. Don't rely on just the jack for support.
Step 2 - Remove the Old Hinge Pins
First, take the spring compressor and remove the spring from the hinge. Set the spring aside in a safe place as you will reinstall it later. Next, remove the retaining clip holding the hinge pin in place. You can use a slotted screwdriver or needle-nosed pliers for this. Place the pointed end of the metal punch against the bottom of the lower hinge pin. Use a firm strike with the hammer in an upward motion. Use enough force to dislodge the hinge pin but not enough force to damage the hinge or the door frame. Remove the old brass bushings from the lower hinge.
Repeat these procedures for the upper hinge assembly. Inspect the upper and lower hinges, making sure they are not damaged otherwise you might have difficulty installing the new hinge pins.
Step 3 - Install the New Hinge Pins
Apply a good coating of auto grease on the car door hinge pins, bushings, and springs prior to installing them in the hinges. This will make the installation much easier and the hinge will operate smoothly for a longer time.
Starting with the upper hinge, slide the new brass bushings into the hinge. Insert the car door hinge pin into position just as the old hinge pin was prior to removal. Secure the hinge pin in place with a few firm taps from the hammer. Again, use just enough force to set the pin but not enough to damage the hinge. Secure the hinge pin with the retaining clip, hammering it into place. Lastly, reinstall the hinge spring. Repeat these procedures for the lower hinge assembly. Wipe off any excess grease from the door hinge assembly after installation.
Perform this simple procedure on all the doors of your car. Chances are if one hinge pin needs replacing, all the car door hinge assemblies will need replacing soon.
