If the drums on your garage door are shifting from their position when the door goes up and down, causing the cables to scratch the door, there could be a few potential causes for this issue:

Loose drum set screws: The drums are typically secured to the torsion tube with set screws. If these set screws are loose, it can cause the drums to shift during door operation. Check the set screws on both drums and ensure they are tightened securely.
Worn or damaged drum grooves: Over time, the drum grooves can wear down or become damaged, causing the cables to slip out of position. Inspect the drum grooves for any signs of wear, burrs, or damage. If necessary, consider replacing the drums to ensure proper cable alignment.
Improper cable tension: The tension of the cables is important for smooth operation and proper alignment. If the cables are too loose or too tight, they can cause the drums to move from their position. Make sure the cables are properly tensioned according to the manufacturer's recommendations.
Misaligned or damaged tracks: Examine the tracks to ensure they are properly aligned and not bent or damaged. Misaligned or damaged tracks can affect the movement of the door and contribute to drum shifting. Adjust or repair the tracks as needed.
Insufficient drum bearings: The drums should be equipped with bearings to allow smooth rotation. If the bearings are worn out or insufficient in number, it can cause the drums to move during door operation. Check the condition and quantity of the drum bearings and replace them if necessary.
If you're unsure about how to address the issue or if it requires expertise, it's recommended to consult a professional garage door technician. They can assess the situation, identify the exact cause of the problem, and provide appropriate solutions or repairs to ensure the smooth and safe operation of your garage door.

Loose set screws, a bent shaft, or misaligned tracks can cause your garage door drums to move inward, scratching the door. Tighten set screws (if accessible) and check for shaft bends. If unsure, call a professional for repairs, especially if springs are involved.
