Garage Door Cable & Roller Displacement
Garage door tracks and rollers typically get bent or damaged in some commonly occurring scenarios. Broken cable and/or cable drum connection. When this happens, and one attempts to close the door, the door will bend sideways and bend the track.
Roller displacement may crop up as a clue pointing to tracks. This results from a lack of lubrication on roller stems. Failure to lubricate these rollers leads to inflexibility, and a bending of the lower portion of horizontal track, with a repair shortly to follow (Many still wonder why the track rollers keep popping out).
Common Causes of Roller & Track Problems
Inside locks can cause scraping on the vertical tracks and can lead to tracks wearing down and becoming damaged. Another issue is rollers seizing up and the ball bearings wearing out causing the rollers to drag in the track instead of roll. A decaying jamb or footing can also cause issues with the tracks shifting and eventually lead your door to be inoperable.
Replacement becomes warranted with these types of accidents.
Metal fatigue in the horizontal track itself. This arises from repeated door weight put on the track.
Normal shifting of the foundation, construction materials, and door parts over time.
