Loose or Broken Garage Door Hinges
Loose or broken garage door hinges are usually a quick, low-cost fix: tighten the lag bolts and nuts holding each hinge, and replace any hinge that's cracked, bent, or rusted through. A noisy door, a panel that sags or catches as it moves, or a hinge with elongated screw holes are the telltale signs. Hinge work is safe to do yourself as long as you stay away from the springs and cables under tension.
Step by step
-
1
Close the door and find the bad hinge
Put the door all the way down so the panels carry no spring tension, then unplug the opener so it can't run while you're working. Look along the seams between panels: hinges are numbered (you'll see a stamped 1, 2, 3, etc.) and sit at the panel joints and the ends where rollers go. Watch for a hinge that's cracked at the barrel, bent, rusty, or pulling away from the panel — that's your culprit.

Tighten before you replace
Most 'broken' hinges are really just loose. Grab a 7/16" socket or nut driver and snug down the lag bolts and any nuts on each hinge. Don't over-torque into the wood-and-steel panel — just firm. If a screw spins freely and won't bite (a stripped or stripped-out hole), the wood or panel is worn; move to step 4 for that hinge rather than cranking harder.

3
Test the door by hand
With the opener still unplugged, lift the door halfway and let go. A balanced door with good hinges holds roughly in place and moves smoothly. If you hear grinding at a joint, see a panel pinch or gap as it bends, or a roller drags, that hinge or its roller needs replacing — note the number so you buy the right part.

Replace a damaged hinge with a matching one
Buy the exact numbered hinge (a #2 is shaped differently than a #4 — they're not interchangeable). With the door fully down, unbolt the old hinge, swap in the new one, and re-torque the bolts. If the screw holes are wallowed out, move the hinge slightly or use slightly larger fasteners so they bite into fresh material. Replace the roller at the same time if it's worn.

5
Lubricate and run a full cycle
Wipe each hinge and apply a garage-door-specific lithium or silicone spray lube to the hinge pins and roller stems — never WD-40, which attracts grit. Plug the opener back in, run the door up and down two or three times, and listen. Quiet, even travel with no catching means you're done.
When to call a pro
Call a pro if more than one or two hinges are cracked, if the door binds or won't stay balanced after the swap, or if the damage involves the bottom-bracket hinges near the cables — those sit under spring tension and can injure you badly.

Can I keep using my garage door with a broken hinge?
For a day or two, maybe — but don't push it. A failed hinge throws the load onto neighboring hinges and rollers, which speeds up wear and can crack a panel or let the door rack out of square. Run it as little as possible until you've replaced the hinge, and stop using it entirely if a panel is visibly sagging or pinching.
How much does it cost to fix garage door hinges?
The hinges themselves are cheap — usually $3 to $8 each at a hardware store, plus a couple dollars per roller if you're swapping those too. If you hire a tech, expect roughly $100 to $200 for a service visit that covers a few hinges and rollers, since most of the cost is labor and the trip charge, not parts.
Why do my garage door hinges keep coming loose?
Vibration from daily up-and-down cycles slowly backs out fasteners, and screw holes in the panels wear oversized over time so the bolts can't hold. A door that's out of balance or has dry, dragging rollers shakes harder and loosens hinges faster, so fixing the balance and lubricating everything makes the tightening last.
What's the difference between numbered garage door hinges?
The number stamped on a hinge tells you which panel joint it belongs to — higher numbers have a steeper offset to match the door's curve as it bends into the horizontal track. Using the wrong number makes the door bind or the rollers ride badly in the track, so always match the number when you replace one.
