My garage door is still squeaking even after lubrication. What should I do?

If your garage door is still squeaking even after lubrication, it means the noise source is not just dryness but wear, looseness, or misalignment that lubrication alone cannot fix. First, disconnect the opener by pulling the red emergency release cord and manually lift the door halfway. If it still squeaks when moved by hand, the problem is in the door hardware, not the opener. Check all nuts and bolts on the tracks, hinges, and roller brackets. Loose hardware vibrates and squeaks even when lubricated, so tighten everything with a socket wrench. Next, inspect the rollers closely. If you have old metal rollers with unsealed bearings, the bearings may be pitted, flat-spotted, or seized internally, and no amount of lube will quiet them. Look for wobbling, cracked nylon, or rollers that do not spin freely. Replacing all rollers with high-quality nylon sealed-bearing rollers often eliminates persistent squeaks. Also check the hinges for elongated holes or cracks. Check the torsion spring for coil binding or rust. If the door is squeaking from the top, the bearing plates may be worn. Finally, check the opener chain or screw for tension and wear. If the door is still noisy, call a technician to check door balance and spring tension.
