How to Lubricate a Garage Door Properly
Use a garage door silicone or white lithium spray on the hinge pivots, roller bearings, torsion spring, end bearing plates, the opener rail on chain and screw drives, and the lock mechanism. Never lubricate the track, which must be clean and dry. Do not use WD-40, which is a solvent that strips existing lubricant.
What to use
A garage door silicone spray or a white lithium grease spray. Both are sold specifically for this and both come with a straw for reaching bearing points.
What not to use: WD-40 or any general penetrating oil. It is a solvent, and its job is to displace what is already there. On a garage door that means stripping grease out of bearings.
Where it goes
Hinge pivot points. Where the hinge knuckle turns. One short spray each, along the pin.
Roller bearings. The small bearing at the centre of the roller, not the wheel. Spray into the bearing and spin the roller.
The torsion spring. Spray along its whole length and let it work between the coils. This reduces friction between coils and it slows corrosion, which matters on the coast.
End bearing plates. The bearings at each end of the torsion shaft, and the centre bearing if there is one. These are frequently missed and they are a common source of grinding.
The opener rail. Chain and screw drives only. A light film along the chain or the screw. Belt drives need nothing.
The lock mechanism, if the door has one.
Where it never goes
The track.
The rollers are supposed to roll along the track, not slide. Grease in the track collects dust, grit and sand, becomes an abrasive paste, and wears rollers faster than no lubricant at all.
Clean the track instead: wipe it out with a dry cloth, or with a rag and a little household cleaner if there is build-up, then dry it.
The method
- Close the door and disconnect the opener with the manual release. Working on a door that can start moving is a bad idea.
- Wipe the track clean and dry.
- Work through the six points above, a short spray each. More is not better; excess drips onto the car.
- Wipe up overspray, especially anything that reached the track.
- Reconnect the opener and run the door twice to distribute everything.
- Listen. If a specific noise remains, you have found the part that needs more than lubrication.
Fifteen minutes, twice a year.
What lubrication will not fix
It will not fix a spring that has lost tension, a cable that is fraying, a bent track, a cracked hinge, or a roller whose bearing has already failed.
If the door is quieter for a week and then noisy again, the lubricant is masking a worn part rather than solving anything. That is the point at which a tune-up at $95 to $180 is worth booking, because whatever it is will be cheaper now than after it seizes.
Related questions
How often should I do this?
Twice a year for a door in daily use. Spring and autumn, and the autumn one matters most in New York because it goes into winter properly lubricated.
What about nylon rollers?
Lubricate the bearing at the centre of the roller, not the nylon wheel itself. Oil on the wheel picks up grit and makes it slip in the track.
Why not WD-40?
WD-40 is a water displacer and solvent. It dissolves and displaces the grease already in the bearings, so the door goes quiet for a week and then runs drier than before.
