Keeps your garage door running smoothly.
The most common cause for end bearing plate failure is poor installation. They’re not designed to have any tilt, so they need to be mounted straight up and down.DIY Repair

#2 Torsion Springs

Torsion springs are most commonly mounted horizontally above the opening of your garage door. When the door is pulled down, cables attached to the bottom corners force the springs to wind up, in turn energizing the system. If your garage door is hard to lift with one hand, you most likely have a broken torsion spring.

**Spring replacements can be very dangerous. Please contact a licensed professional.

GDU Expert Tip
A spring that’s too strong will cause cables to jump off the drum. One that’s too weak can cause the cables to unwind.

#3 Torsion Spring Tube
