1. Check and Tighten Hinges:
* The most likely culprit: Start by carefully inspecting all three hinges on each door. Look for loose bolts.
* Tighten them: Use a socket wrench and tighten all the bolts on each hinge. Don't overtighten, as you could strip the threads. Work systematically, tightening one bolt at a time on each hinge. Sometimes, simply tightening these will resolve the issue.
* Check the Hinge Pins: Make sure the hinge pins aren't bent or worn. If they are, replacement is necessary. You might need to carefully tap them out with a punch and hammer.
2. Adjust the Hinges:
If tightening doesn't fix the sag, you might need to adjust the hinge position. This usually requires loosening the bolts slightly to allow for repositioning.
* Locate the Sag: Determine which part of the door is sagging most – top, bottom, or both.
* Top Sag: If the top of the door sags, slightly loosen the bolts on the bottom hinge and raise the door slightly. Then retighten the bolts.
* Bottom Sag: If the bottom of the door sags, slightly loosen the bolts on the top hinge and lower the door slightly. Then retighten the bolts.
* Multiple Points of Sag: Adjust multiple hinges as needed to get an even alignment. This might require some experimentation and patience.
* Door Striker Adjustment: Sometimes, the door striker (the metal plate the door latch engages with) might be misaligned. You can usually adjust this with a screwdriver to bring it closer to the door latch.
3. Replace Worn Hinges:
If tightening and adjusting don't solve the problem, the hinges are likely worn. Replacement is the only solution.
* Obtain Replacement Hinges: Get new hinges that are specifically for your 1995 Chevy truck model. Parts stores can help you find the correct ones.
* Removal and Installation: This is a more involved process, requiring removing the door panel (to access the hinge bolts from the inside), and then carefully removing and replacing the hinges. There are numerous online videos demonstrating this process for similar trucks; searching for "1995 Chevy Truck Door Hinge Replacement" on YouTube will likely yield helpful results.
4. Check Door Alignment:
In rare cases, the door's frame itself might be slightly bent or damaged, causing alignment issues. This would require more serious bodywork repair.
Important Notes:
* Safety First: Always use jack stands when working underneath your truck. Never rely solely on a jack.
* Tools: You'll need a socket wrench set, screwdrivers (Phillips and flathead), a hammer, punches (if replacing hinge pins), and possibly a pry tool for removing door panels.
* Patience: Door alignment can be fiddly. Don't rush the process; take your time and make small adjustments as needed.
* Professional Help: If you're uncomfortable working on your truck, take it to a qualified mechanic.
By systematically working through these steps, you should be able to fix the sagging door on your 1995 Chevy truck. Remember to consult a repair manual or online resources specific to your truck's model for detailed diagrams and instructions.
