Where Lubricant Goes, and Where It Must Not
Start with the mistake almost everyone makes: do not grease the track. The rollers are meant to roll along it, not slide through a paste of grease and driveway grit. A greased track collects dirt within weeks, the wheels start skidding instead of turning, and the noise gets worse rather than better.

The track gets wiped clean instead. Everything that pivots, spins or slides gets lubricant, and which lubricant depends entirely on which part you are standing in front of.
The Points, One at a Time
Hinges take a drop at each pin where the two leaves meet. Open-bearing roller stems take a small amount at the bearing itself, while sealed nylon rollers take nothing at all — they are closed units and adding grease only gives dust somewhere to stick. The torsion spring gets a light coat along the coils so they do not bind against each other as they wind.
The end bearing plates at each side of the shaft and the centre bearing take a proper bearing lubricant, and the lock bar and any side latch get a shot. The lift cables and drums get inspected but never greased — oil on a cable hides exactly the fraying you need to be able to see.
Product matters as much as placement. A white lithium grease or a purpose-made garage door lubricant stays where it is put and keeps working. Thin penetrating sprays flush out the grease that was already in the bearing and leave nothing behind, which is why a door treated with one goes quiet for a fortnight and then comes back louder than it started.
Opener Drives Each Want Something Different
Chain drives want a light coat of grease along the chain and the rail it runs on. Belt drives want nothing whatsoever on the belt — grease does rubber no favours and picks up grit. Screw drives are the fussy ones: they need a specific synthetic lubricant along the threaded shaft, and ordinary household grease thickens badly on them in cold weather.
The trolley and the section of rail it slides along take a wipe of grease either way. If the opener strains at the same point on the rail every single time, that is not a lubrication problem and it gets diagnosed properly instead of sprayed at.
Cold Thickens Whatever You Have Put On
An attached garage with no heat of its own tracks close to the outside temperature all winter. Grease that was ideal in July stiffens by January, and a door that ran quietly through autumn starts groaning on the first cold morning and moving slower than it did.
That is the argument for doing this going into the cold rather than in spring, and the argument against over-applying. A thick layer of heavy grease drags harder at low temperature than a thin correct one. Twice a year suits most doors here. Make it three if everyone comes and goes through the garage rather than the front step.

Questions
Buffalo Grove questions about this job
Is WD-40 alright to use on a garage door?
Not as a lubricant. It is a penetrating solvent, so it strips grease out of hinges and bearings and evaporates, leaving those parts drier than before. It has a legitimate use freeing a seized lock or bolt, but anything you loosen with it needs proper grease afterwards.
It went quiet after lubricating and got loud again quickly. Why?
Either the wrong product was used, or the noise was never coming from friction. A worn roller bearing, a cracked hinge or a door whose springs have stopped taking their share of the weight will all quieten briefly under fresh lubricant and then come back, because the lubricant masked the wear rather than removing it.
Can lubrication fix a door that has become slow?
Sometimes, if the door has simply been dry for years and everything is dragging. More often a slow door is a spring that has lost tension, so the opener is now hauling weight it was never meant to carry. Lubricant helps, then the underlying cause needs finding.
