8.5 Inspect the bearing. Lube it with motor oil, spray lithium, or spray lubriplate grease. Do not use WD-40. If the shaft is worn and the bearing is seized and you can't free it, replace the bearing. Or, if you have bearings labeled "ADH" we recommend replacing them. I find very few other bearings that need to be replaced. However, if you do need to replace the bearing and you do not have a new one, you can replace it at a later date. You'll find a quick way to do this at our End Bearing Plate Replacement instruction page.

Center and level the first section after you install the brackets. The door must be level even if the floor isn’t, so use shims under the section to level it. The rubber gasket on the bottom section will fill the gaps created by an unlevel floor. To hold the level in place, tape it to the section. To hold the section in place, lightly toenail a 16d nail into the frame and bend it over the section. Add brackets and rollers before setting them in place and stack one section on top of another, toenailing as you go up. https://www.youtube.com/attribution_link?a=Z_eZc-kh40c&u=%2Fwatch%3Fv%3DXXXXXX%26feature%3Dshare
To install a single new garage door it should cost between $500 and $800. They demonstrate that the average homeowner can usually tackle such a project in a nine hour time span and a professional will be able to complete it in roughly five hours. Should it be a DIY project? Not really, most housing experts point out that it is a two-person job, requires advanced carpentry skills, and even knowledge of household electronic systems.
Measure the various areas where the door will be installed: door-opening height and width, headroom (from top of opening to ceiling), and back room (length of garage). For the headroom, you should have about 10" to 12" of space, depending on the spring system you're installing. For the back room, you should have the door height, plus another 18" or more of space.

If one of your door springs just broke and you are looking for instructions to decide if you can change the spring or springs safely and correctly, this page should help. DO NOT OPEN AND CLOSE YOUR GARAGE DOOR. Wooden garage doors are heavy and will probably damage or ruin the opener. The tops of steel doors often bend when operated with broken springs.

Extension springs are long, lighter-weight springs that run perpendicular to the door and are mounted above the horizontal portions of the door tracks. These springs are tensioned by stretching out, using cables and pulleys, as with the torsion system. Because extension springs are merely suspended between two brackets (they are not mounted to a rod, like torsion springs), they must have a safety cable running through each spring. This helps contain the spring in the event of a breakage. Without the safety cable, a spring breaking under tension is a very serious safety hazard. If you have old springs that don't have safety cables, you should install them even if you aren't replacing the springs.
Test the door balance. A garage door should require only a few pounds of pressure to move it up and down. If springs wear out and lose their resiliency, a power garage door opener may need to work extra hard to lift the door. This can quickly wear out the motor on the opener. Replacing worn-out springs is usually a job for a professional technician.
These instructions are for doors with cable drums and cables that look similar to those in the picture below. The next part beyond the end of the spring assembly is the cable drum. The drum is cast aluminum alloy 4" in diameter and 12.6" in circumference around the flat portion. Just beyond the cable drum is the end bearing plate. The cable unwraps off the back of the drum between the drum and the garage wall or jamb and travels down alongside the door, inside the track brackets and behind the roller stems as shown.
9.13 If you have a spring anchor bracket with a fixed steel bearing, check for wear at the point where the shaft and bearing race meet. The shaft needs to be free to slide sideways inside the bearing. File the shaft if needed. Lube the bearing. Notice that only one bearing is needed for two torsion springs. This bearing keeps the shaft from rubbing against the inside of the stationary cones and on the center bracket. Your garage door may not have a center bearing. If so grease the shaft where it will be rubbing the bracket and the insides of the cones.
Many jobs around the house are fairly easy fixes. It’s relatively easy to clean out your fireplace, clean the leaves from the gutters or repaint a wall. It’s a different thing to replace your garage door spring. It’s careful work that is almost impossible to do correctly the first time. Garage door professionals spend a great deal of time learning how to do it properly, and even the most detailed instructions won’t make you an expert in the span of a few hours. It can be almost infuriatingly annoying at times and is simply better left to professionals.
Garage doors are able to move due to a counterbalance system that usually consists of a torsion spring. We often find incorrect springs have been installed which result in an unsafe door that you may not be able to open manually when needed. The balance of your garage door should be tested annually to reduce wear on your garage door opener and ensure it can be opened if an emergency situation arises. Because of the dangers involved with torsion springs, garage door spring repair and installation should only be done by experienced professionals like our Medics.
