Easy step-by-step instructions to show you how to replace a garage door torsion spring safely. If your garage door torsion spring is indeed broken, you can replace it yourself and save quite a bit of money, as long as you have the right tools and parts, follow the right steps, and take proper safety precautions. That’s how DIY Garage Door Parts can help. We’ll show you how to release tension from your existing torsion springs, remove the springs from the torsion bar and install the new torsion springs – safely and properly.
Here are the tools you need to replace a broken garage door torsion spring:
- Two winding bars. You need these to remove tension from the existing springs at the beginning of the project and add the proper tension to the replacement torsion springs at the end.
- Vise grips. This will keep the torsion shaft from falling out when you remove the old springs.
- Wrenches: 9/16, 1/2, and 7/16 inches, 3/8-inch square head, or eight-point socket.
Before you get started, keep in mind that the second unbroken spring still has tension, so wear safety goggles and have your winding bars in the torsion spring before you loosen any tension.
