TIGHTENING LOOSE PARTS
You need to first make sure that all the parts of the door are securely fitted to their respective places. Tighten all the screws and nuts on and around the door using a deep socket wrench and a ratchet. However, you need to be careful when tightening the nuts and make sure that you do not over tighten the nuts as you may end up ruining their threads or even damaging the material they are screwed on to.
ROLLER AND HINGE MAINTENANCE
The noise may be because of worn out rollers and hinges. Nothing lasts forever and thus these hinges and rollers tend to age with time. They may become worn due to dust in the garage’s environment or humidity in the air that eventually leads to the rusting of these parts. When the wear becomes excessive, the rollers tend to shake and wobble as the door closes and opens.
If this is the case, you need to replace them and you can instead use nylon rollers that come with sealed bearings. These are more efficient as they less noisy and do not necessarily require periodic oiling like the steel bearings. These nylon rollers and bearings can be purchased from your nearest hardware store. However, you should note that they are more costly in comparison to the regular steel bearings.
LOOSE GARAGE DOOR CHAIN
You also need to check the garage door chain that is used to open the door. A loose chain is responsible for most of the noise and the jerky movements the door makes as it operates. The jerky movements in turn are responsible for thrashing the rollers on to their tracks. Tighten the chain to minimise the noise the door makes and this will in turn solve the roller smacking problem that would have eventually led to damaged rollers. Once this is done, you need to apply grease on to the chain to facilitate easier movement as the door opens and closes. Lubricant will also reduce the wear on the chain itself, thus prolonging its lifespan. Spray the bearings, hinges and springs with a garage door lubricant.
