If it's higher than four feet off the ground, or lower than three feet, you'll know it needs to be realigned. Use a ladder as a brace to keep the door safely open while you're working on it. This also takes the pressure off the springs so you can inspect them for rust and warping.
Because garage doors are used so often, it is important to lubricate them at least once a year. When it comes to garage door lubricants, don't use silicone or grease because that will ultimately make the situation worse. For proper lubrication, use Lithium Grease.
Therefore, it is advisable to use a spray based lubricant for the purpose of lubricating these springs. WD-40 can be use effectively for this purpose, exactly, considering the fact that it is not only a lubricant but also serves to get rid of any rust that might exist on your garage door springs.
