Garage door springs play a crucial role in the smooth operation of your garage door. Over time, these springs may wear out or break, causing your garage door to malfunction. When faced with such a situation, it becomes necessary to replace the garage door springs to ensure your garage door’s continued functionality and safety. In this comprehensive guide, we will walk you through replacing both torsion and extension springs, providing you with step-by-step instructions and essential tips to help you complete the task.

Before we delve into the process of replacing garage door springs, it is important to have a basic understanding of the two main types of springs commonly used in garage doors: torsion springs and extension springs.

Torsion Springs

Torsion springs are typically used in heavier garage doors. They are mounted horizontally above the garage door opening and work by twisting and coiling up when the door is closed. When the door is opened, the stored energy in the torsion springs is released, helping to lift the door smoothly and efficiently.

Extension Springs

Extension springs, on the other hand, are commonly found in lighter garage doors. They are mounted vertically on either side of the door and stretch or extend when the door is closed. When the door is opened, the extension springs contract, providing the necessary tension to lift the door.

Assessing the Need for Garage Door Springs Replacement

The first step in replacing garage door springs is to assess whether or not they need to be replaced. Look out for the following signs that may indicate worn-out or broken springs:

If you notice any of these signs, it is highly likely that your garage door springs need to be replaced. Proceeding with the replacement process is essential to ensure the safety and proper functioning of your garage door.

Tools and Safety Precautions for Garage Door Springs Replacement

Before you begin the replacement process, gather the necessary tools and equipment to ensure a smooth and efficient procedure. Here are the tools you will need:

Additionally, it is crucial to prioritize safety during the replacement process. Garage door springs are under immense tension and can be dangerous if mishandled. Follow these safety precautions:

Replacing Torsion Springs

Now, let’s dive into the step-by-step process of replacing torsion springs in your garage door.

Step 1: Release Tension on the Old Springs

Before removing the old springs, it is crucial to release tension to prevent accidents. To do this, use a winding bar to turn the spring in the opposite direction of its winding. Slowly lower the spring, allowing it to rest on the top bar of your garage door. Repeat this process until the spring has no tension left.

Step 2: Remove the Old Springs

Once you have released the tension on the old springs, it’s time to remove them. Use two 9/16″ wrenches to loosen the bolts that attach the springs to the anchor bracket. Once the bolts are loose and the set bolts on the winding cones are loosened, slide the springs to each side of the shaft.

Step 3: Remove Torsion Spring Drums and Unhook Torsion Cables

Next, loosen the set bolts on the torsion spring cable drums and unhook the cables from the slots. Remove the drums from the torsion bar by pulling the bar towards the opposite side until the drum can slide off the tube. Put the tube back into the wall bracket and repeat the process on the opposite side.

Step 4: Remove the Old Spring

Starting on the right side, slide the old spring to the end of the torsion bar. Push the torsion bar toward the opposite side until it is out of the right-side wall bracket bearing. Once there is enough room, slide the spring off the bar. Place the bar back into the wall bearing bracket and push it through the hole until the opposite side is out of the wall bracket on that side. Repeat the steps on the left side.

Step 5: Install the New Springs

Starting on the left side, slide the new springs onto the shaft in the same manner as the old springs. Ensure that the springs are placed on the correct sides, with the right-wound spring on the left side of the anchor bracket and the left-wound spring on the right side of the anchor bracket.

Step 6: Reset Drums and Cables

Starting on the left side, align the torsion bar back into the bearing on the wall bracket. Line up the drum with the previously made indentations and secure the set screws. Place the cable back in the drum slot and wind it onto it until it is taut. Once the drum is attached to the torsion tube and the cable is reset, lock the bar with a vice grip. Repeat the steps on the right side without needing a vice grip.

Step 7: Attach New Springs to Anchor Bracket

Put the bearing back inside the hole on the anchor bracket and line up the spring anchor plugs on both sides. Insert the mounting bolts through the holes on both springs, with the anchor bracket in between. Tighten the nuts and bolts securely using two 9/16″ wrenches.

Step 8: Wind the New Springs

Once the new springs are in place, it’s time to wind them up. Insert a winding bar into the winding plug and rotate it 1/4 turn upward while holding it securely. Insert a second winding bar into the plug, take up torque load, and remove the first winding bar. Repeat this process until the springs are wound the correct number of 1/4 turns based on your door’s height.

Step 9: Release the Vice Grip on the Torsion Bar

Once both springs are wound up and secured, release the vice grip on the torsion bar.

Step 10: Test the Garage Door

To ensure that the new springs are working correctly, test the garage door by opening and closing it a few times. If the door opens and closes smoothly without any issues, then the new springs are installed correctly.

Replacing Extension Springs

If you have a garage door with extension springs, follow these steps to replace them:

Step 1: Release Tension on the Old Springs

Before you can remove the old extension springs, release the tension on them. Start by opening the garage door fully and securing it in place using clamps or vice grips. This will ensure that the tension is released from the springs.

Step 2: Remove the Safety Cables

If your extension springs have safety cables, start by removing them. Loosen the cables from the wall or angle iron and allow the springs to fall to the floor. Be cautious as the falling springs can cause damage to your car or other possessions. Hold onto the safety cables as you loosen and remove them.

Step 3: Remove the Old Springs

Once the safety cables are removed, proceed to remove the old extension springs. If necessary, loosen the bolts securing the springs to the anchor bracket. Slide the springs out from the brackets and carefully lower them.

Step 4: Install the New Springs

To install the new extension springs, follow the reverse process of removing the old springs. Slide the new springs into the brackets, ensuring they are securely in place. If needed, tighten the bolts to secure the springs.

Step 5: Reattach the Safety Cables

If your garage door requires safety cables, reattach them to the new extension springs. Secure the cables to the wall or angle iron, ensuring they are properly tensioned and will prevent the springs from causing any damage in case of breakage.

Step 6: Test the Garage Door

After replacing the extension springs, test the garage door by opening and closing it a few times to ensure smooth operation. If the door functions properly without any issues, you have successfully replaced the extension springs.


Replacing garage door springs is a task that requires caution, precision, and knowledge. Following the step-by-step instructions in this guide, you can confidently replace torsion and extension springs in your garage door. However, it is essential to prioritize safety and seek professional assistance if you still determine any aspect of the replacement process.
