Garage Door Making Loud Noise in Chattanooga? Causes & Fix

**Loud BANG (one-time).** Almost always a snapped torsion spring. Don't operate the door—call us.

**Grinding from the opener head.** Stripped main drive gear. Common on 8–12 year-old LiftMaster and Chamberlain chain drives.

**Squealing / squeaking.** Dry rollers, hinges, and bearings. A lube service usually cures it; if rollers are nylon-on-steel with flat spots, they need replacement.

**Popping along the tracks.** Worn nylon or steel rollers bouncing on a track joint. Replace with sealed 13-ball nylon rollers.

**Rattling / vibrating.** Loose track lag bolts, loose hinge screws, or loose strut bolts. A 20-minute tightening pass usually solves it.

**Scraping on the seal.** Bottom astragal or side weather seal has hardened. Cheap fix.

We re-tighten every hinge, track bolt, strut, and motor mount; lube hinges, springs, bearings, and rollers with the right lithium-based grease (never WD-40); inspect rollers and recommend replacement only if needed. Most doors lose 70% of their noise in under an hour.
