How to lubricate a garage door
So, you’ve settled on either silicone based lubricant or white lithium grease, right? Well now it’s time to get lubricating. If you’ve decided on a spray lubricant, your job will be made a bit easier. Especially with a straw nozzle, your can will allow you to get into the tightest of spots around the door.
Preparation: Move any vehicles or other obstructions either out of the garage or out of your way. We suggest you do this not only for safety’s sake, but also to mitigate grease overspray or dripping.
It’s recommended that you lubricate the door parts with the garage door closed and released from the motor. You’ll be applying the grease at the pivot points so you’ll want it to be free-moving.
Lubricating: Starting at the top, spray or apply your grease to the following parts attached to the door itself:
Here are the parts that you should spray with WD-40 Multi-Use-Product:
- Springs: Spray WD-40 generously on all the springs. Just make sure they are covered and not soaked
- Hinges: Lubricate the points where the hinges pivot. However, make sure you do not apply lubrication to plastic hinges as they can degrade with it
- Rollers: Apply WD-40 as a garage door lubricant thoroughly to the rollers of your garage door.
- Locks: Cover the locks fully in the lubricant if you have trouble opening and closing them
As you work your way down, raise the garage door and apply the grease to the hinged pieces. This not only makes it easier for you to work, but maximizes the amount of grease that gets inside all the now-exposed parts. Use your step ladder to increase your reach but also to get a better view of parts you’re lubricating.
If you have metal rollers, you’ll want to inspect them closely where the stem meets the back of the roller wheel. You should see some small bearings inset within the wheel. Spray or carefully apply lubricant to these bearings. If you have nylon rollers, there may be no need to lubricate this point of contact as the bearings are likely sealed.
In either case, do not lubricate the track. Did you read that? Don’t lubricate the track. We can go through with a rag and wipe this down when we’re done, but don’t directly lubricate the track. You’ve got a nearly 300lb. door and you don’t want it sliding around, or worse, coming completely off the track.
Next, you can go ahead and lubricate the pulley. This will be the large wheel with the coiled-up wire attached to the garage door. Just like the metal rollers, you may see some exposed bearings that can be sprayed. If the bearings are sealed then there is no need to lubricate this part
The arm bar is attached to the carriage rail by a metal sleeve. The point of contact is on the top of the carriage rail. There is no need to lubricate the metal (bottom) facing you. Spray or apply a line of grease along the top of the carriage rail.
