Is your car door starting to droop, making it difficult to close or align properly? A sagging car door is a common issue, especially in older vehicles, often caused by worn-out door hinges. While you might think of expensive hinge replacements and complicated door realignments, there’s a surprisingly simple and cost-effective solution: using washers. This guide will show you how to repair a sagging car door using just a few dollars’ worth of washers and bolts, and about 10 minutes of your time. Forget about costly repairs and extensive labor – let’s get your door back in shape with this easy DIY method.
Tools You’ll Need
Before we begin, gather these simple tools:
- Combination wrench: Ratcheting wrenches will definitely make the process faster and easier, especially in tight spaces.
- Bolts (2): You’ll need two new bolts, slightly longer than the originals.
- Washers (at least 2, possibly more): These are the key to fixing the sag!
- Lock washers (2, optional but recommended): To ensure a secure fit and prevent loosening.
Step-by-Step Guide to Repairing a Sagging Car Door
Follow these steps to lift your sagging door and restore its alignment:
Step 1: Remove One Bolt on the Lower Hinge
Start by focusing on the lower hinge. Locate the bolts connecting this hinge to the car door itself. Typically, there are two bolts. Using your wrench, remove just one bolt from the lower hinge.
Step 2: Source Washers and Slightly Longer Bolts
Take the bolt you just removed to your local hardware store. Find washers that fit snugly onto the bolt. You’ll also need to purchase two new bolts of the same size and thread pitch as the original, but slightly longer (about 1/8″ to 1/4″ longer). This extra length is crucial to accommodate the added thickness of the washers. For reference, some car models like P10s use M8 x 1.25 pitch bolts with a 12mm hex cap, but always confirm the correct size for your vehicle.
Step 3: Prepare the Door and Hinge for Washer Insertion
Park your car on a level surface. Open the sagging door and use a jack to gently lift the outer edge of the door, furthest from the hinges, by approximately 1 inch. This is just enough to relieve pressure on the lower hinge and make it easier to work with.
Step 4: Remove the Second Bolt and Create a Gap
Now, remove the second bolt from the lower hinge. Jack up the door a little bit more. The goal is to create a small but noticeable gap between the car door and the lower hinge. This gap is where you will insert the washers.
Step 5: Insert Washers and Install the New Bolt
This is the core of the repair. Take a washer and insert it into the gap you created, positioning it between the hinge and the car door. With your other hand, take one of the new, slightly longer bolts (and a lock washer, if using) and insert it through the washer and into the bolt hole.
Step 6: Repeat for the Second Bolt and Tighten
Repeat the previous step for the second bolt hole on the lower hinge, adding a washer and securing it with a new bolt and lock washer. Once both bolts are threaded in by hand, carefully lower the jack. Now, use your wrench to fully tighten both bolts.
Step 7: Check Door Alignment and Add Washers if Needed
Close the car door gently to check its alignment. If the door is still sagging, you might need to add more washers. If additional washers are required, always add the same number of washers to both bolts on the lower hinge to maintain even alignment. Avoid using different numbers of washers on each bolt as this can lead to uneven stress and alignment issues.
Your door should now be properly aligned and free from sagging!

How It Works: Understanding the Sagging Door Fix
To understand why this simple washer trick works, let’s visualize the problem. Over time, the hinge pin and bushings in your car door hinges wear down. This wear introduces slack, causing the door to drop or sag slightly at the hinge point.
As the hinge wears, this wear is what leads to the sagging.
By inserting washers between the lower hinge and the car door frame, you are effectively re-angling the hinge. This slight adjustment compensates for the wear in the hinge, lifting the door back into its original, aligned position.
Conclusion
Repairing a sagging car door doesn’t have to be a complicated or expensive task. With just a few simple tools and inexpensive washers, you can effectively fix the problem in minutes. This DIY method is a testament to simple yet effective solutions in car maintenance. So, before you consider costly hinge replacements or professional repairs, try this washer trick and bring your car door back to its proper alignment and smooth operation.
