How to Replace the Hinge Pins on a 2001 Blazer
- 1). Place masking tape on the inside edges of the door, on both the inside and outside of the door.
- 2). Remove the door spring by using a door spring removal tool. Insert the tool into the door spring, turn the knob with a screwdriver to compress the spring, then pull out the tool.
- 3). Set a 5-gallon bucket under the door. This will help support the weight of the door.
- 4). Place a nail punch under the hinge pin, and strike it with a hammer. Repeat this until the hinge pin begins to come out of the hinge.
- 5). Place the end of a flat-head screwdriver under the top of the hinge pin, then strike the screwdriver with the hammer to force the hinge pin out of the hinge.
- 6). Place the bushing on top of the new door hinge pin, and tap it into place with the hammer.
- 7). Insert the new hinge pin into the hinge. Tap on the hinge pin with the hammer and nail punch to force the pin into the hinge.
- 8). Insert the hinge spring back into the door, and release the tension on the spring removal tool.
- 9). Spray the door hinge with a lubricating spray or apply grease.
