Get it right the first time!

Let's begin.

1. Open the garage door.
2. Attach a vise-grip to the track or support door with ladder or board.
3. Loosen the nut below the bottom of the first spring.
4. Remove the old spring.
5. The top pivot bolt on some doors has bearings that are worn. If your bearing or shaft is worn, replace it with bolts, nuts, and washers, and lubricate with wheel bearing grease as pictured.
6. Install the new spring.
7. Tighten the nut to its original position.
8. Repeat the process with the other spring.
9. Test the springs and adjust the bottom nut on each spring as needed.
