Here's a breakdown of how to adjust door pins, focusing on addressing common door problems:
1. Identify the Problem:
Before you start, determine *why* you need to adjust the pins. Common issues include:
* Door won't latch: The door might not close completely, or the latch might not engage properly.
* Door binds or rubs: The door might scrape against the body when opening or closing.
* Door sags: The door might hang lower than it should.
2. Tools You'll Need:
* Jack and jack stands: To safely lift the vehicle.
* Socket set: Likely need a variety of sizes, depending on the specific bolts you encounter.
* Screwdrivers: Phillips and flathead, possibly.
* Pliers: For gripping and adjusting the pins.
* Penetrating oil (like PB Blaster): To loosen any rusted or seized bolts.
* Wrench(es): To tighten or loosen bolts, possibly.
* Flashlight: To see inside the door jamb.
3. Accessing the Door Pins:
The door pins are usually located at the top and bottom of the door. They are often concealed by plastic covers or caps. You may need to:
* Remove the interior door panel: This gives you much better access to the pins and any adjustment mechanisms. There are plenty of online resources with videos showing how to remove the interior panel for a 1998 Chevy Blazer. Search YouTube for "1998 Chevy Blazer door panel removal".
* Locate the adjustment bolts/screws: These will be on the hinges themselves. They allow for slight up/down and in/out adjustments.
4. Adjusting the Door Pins:
* Top Hinge: Adjusting the top hinge often controls the main alignment of the door. Loosen the bolts on the top hinge slightly. Then, make small adjustments (usually by tapping the hinge with a hammer or using a wrench for more precise adjustments) to move the door up, down, in, or out. Tighten the bolts securely after each adjustment and test the door.
* Bottom Hinge: The bottom hinge typically influences the door's vertical alignment and helps to control the gap. Similar to the top hinge, loosen the bolts, make small adjustments, and then re-tighten.
* Striker Plate: If the door doesn't latch properly, you may need to adjust the striker plate (the metal piece on the door jamb that the latch engages with). This might involve loosening its screws and slightly repositioning it.
5. Testing and Iteration:
After each adjustment, close and open the door several times to check the fit. Make small adjustments until the door closes smoothly and latches securely without binding.
Important Considerations:
* Rust and Corrosion: Older vehicles are prone to rust. Applying penetrating oil before attempting to remove or adjust any bolts will significantly help.
* Small Adjustments: Make only small adjustments at a time. Over-tightening can damage the hinge or bolt.
* Professional Help: If you're uncomfortable working on your vehicle, or if you can't resolve the problem after trying these steps, it's best to take your Blazer to a qualified mechanic.
Remember to consult a repair manual specific to your 1998 Chevy Blazer for detailed diagrams and instructions. These steps provide a general guideline, and your vehicle's specific setup might require slight modifications.
